Triply is kidnapped by gunmen that attacked his convoy. And a rare se lest ri yal show of the shadow falling across the moon. Hello. Ukraines interim president says kiev has begun what he describes as an antiterrorist operation in the north region. Pro russian groups seized more than a dozen buildings in several ukraine cities. This isonetsk at dawn break today. The president has told the Ukrainian Parliament the operation will be conducted in what he called responsible manner, stage by stage to a attempt to stop the attempts to tear the country apart. In another development, president putin has rejected allegations. He said to president obama the allegations were not founded. We have spent days in the city east not far from the russian border. Reporter a Police Station on the streets of ukraine. Outside theres a battle for control. A shot rings out. This was on saturday morning where it all began. That man in the blue jacket is is a local journalist. They decided hes an enemy of of their cause. In towns across this region, angry pro russian protectors take over government buildings. We arrived just afterwards. Our car was stopped by the same crowd. Theyre extreme willy aggressive. They just saw us with our camera. They threatened us, broke our memory chip, told us to get in the car and get out of here immediately. What is now a familiar pattern, we got news Police Station as were falling to protestors in other towns as well. We went to find journalists that fled in search of safety. Ill carry on. Im used to this. Ive had death threats, threatening notes and text messages. Someone threw a rock through the wind screen of my car. Russia denied sending special forces to Eastern Ukraine. Who were the men that seized the Police Station . There were about 100 of them, 10 to 15 guys clearly soldiers that arrived in a mini bus. I couldnt tell if they were russian or ukrainian. The rest were local guys wearing military fatigues. We returned the following day. The protestors had barricaded themselves inside the police compound. We got permission to go in and film whats the center of this rebellion. Men at the gate referred to the commander by his nickname. These were clearly local guy, not special forces on open display in crimea. They were armed. We saw at least aing rifles and they appeared to have taken from the armory inside the Police Station. These men said they were old friends from the local school. There was nothing organized about it says the carpenter who heard what was happening on tv, jumped in the taxi and came here. His friend, a car mechanic, admitted they took weapons out of the Police Station, just to defend ourselves, he says. The men seen here taking over the Police Station in the nearby town. Could these be the Russian Special force . They certainly look for discipline and better armed than the local activists. Might this be the men with the big guns going in first and retreat the locals to hold the building . The protestors remain in control of the Police Station. Separatists occupy a dozen buildings a krocross the region. What happens now inside the police compound is crucial to the future of this country. If this standoff can somehow be resolved peacefully, theres hope for a united ukraine east and west together. If this place is stormed, if these barricades are broken down and there are mass casualty, the ramifications will be felt hard and for a long time to come. Kiev is losing control. Any crack down could become pretest for russian invasion. One false move couldle lead to war. Bbc news. Well, this is how ukraines president announced the operation in ukraine to the parliament in kiev just a short time ago. Translator an antiterrorist operation began this morning in the north of the reejen. It will be conducted stage by stage in a responsible and weighed manner. The objective of these steps i stress once again is to protect ukrainian citizens to stop the terror, stop the crime, to stop the attempts to tear our country apart. Well that was the acting president of ukraine. Well keep you up to date. Five days of intense crossexamination have finished for the parra limpic athlete Oscar Pistorius. Hes been questioned about the night he shot his girlfriend in the bathroom. Nel ended by accusing pistorius of knowing full well reeva was behind the toilet door and he had deliberately gone to find a door and shoot her. We also have the defense questions and no further questions now to the athlete. Karin is in pretoria following the questions of the last few days. Its a lot of pressure on Oscar Pistorius. The whole point of the prosecution to pick holes and find inconsistencies in his version of events. Reporter yes, geeta, Oscar Pistorius must be a very relieved man. He has spent seven days on the witness stand and five have been under crossexamination from the fearsome and relentless gerrie nel the state prosecutor, picking holes in his version of events that night. All through today, the final day of crossexamination, using that word improbable about Oscar Pistorius version of events. Gerrie nel wraps up crossexamination with a summary of the states case, what they believed happened that night. He put hit to Oscar Pistorius. His argument for how the killing of Reeva Steenkamp came to be. You shot four shots through that door knowing whos standing behind the door. Thats incorrect. You knew she was talking to you. Thats incorrect my lady. She got into the bathroom and you armed yourself for the sole purpose of shooting and killing her. Lady. She locked herself in the toilet. You armed yourself with the sole purpose of shooting and killing her. Thats what you did. Not true my lady. Afterwards you overcome by what youve done, that is true. That is true my lady. Only because it was your intention to kill her. You realize that . Opposite my lady. Thank you my lady. I have nothing further. Reporter that was the end of gerrie nels prosecution. Barry roux the lead Defense Council got to his reexamination of the defense witness. That was brief. The aim is to try to address the issues that have risen during the crossexamination and to address any doubts and any inconsistencies. There have been many according to gerrie nel. Barry roux on one particular problem gerrie nel said Oscar Pistorius had with evidence that yesterday he was changing defense. He said in one sentence he shot Reeva Steenkamp because he thought she was an intruder and another sentence it had been an accident. Today barry roux asked pistorius to explain what he meant when he said it was an accident. Could you explain to the court if you talk about accident, what is it you mean by that . I mean the situation. The situation as a whole. It wasnt meant to be. Now, when you were standing with your firearm pointing to the toilet door, what emotions did you experiment . I was terrified. I feared for my life. Scared, thinking about what could happen to me and reeva. I was extremely fearful, overcome with sense of terror and vulnerability. One of the things oscar said during his time on the stand, he read out a valentines card from Reeva Steenkamp waiting for him the morning after the night she died. It said in it she decided it was a good time to tell him she loved him. He read those words out to the court. Possibly the defense wants to be the lasting memory of his testimony. That brought his time on the stand to an end. Of course Oscar Pistorius denies killing Reeva Steenkamp on purpose and the prosecution alleges he killed her in a fit of an argument. The court adjourned until 5 15 local time. Were expecting to hear 14 to 17 other witnesses for the defense, many of them experts. They will be brought to the stand in the next begin in the next hour or so. The two of theres been an application for the court to adjourn thursday until may 5th to have more than two weeks off because of the easter break. The judge is considering that application and will give investigator on that tomorrow morning. Were expecting a sequence of defense witnesses. For Oscar Pistorius, his time on the stand is over. Karin thanks very much live in pretor pretoria. The u. S. Navy says a Remote Control satellite has found no sign of mh 370. It exceeded the operating limit and cut short. Phil was told the aborted mission is not a major setback. There was no material problem, no failure of the seas system. It was just an oversite in the programming. Something we werent expecting with the water depth. We have adapted. Well relaunch the system as soon as the weather clears. We have analyze had the material, that side scan sew so nar results. Be the bottom is filthy. There are rocks. In the area we recovered there was no evidence of aircraft at that site. We have about 70 of that first assigned search area to go look at. Once we relaunch the system it will go do. What extend are you confident otherwise the wreckage will be found using this underwater technology . It could definitely result we dont have evidence of the aircraft and need to step back, reassess the search plan and figure out how to conduct the more strategic Long Duration, longer extensive survey. If the effort is Strong Enough certainly its going to take tenacity if our official instincts, initial detections dont point us in the right directions. Its going to be a Long Duration search. How long are you prepared to keep looking . My current tasking is basically pursue the high priority detections or high priority areas. After that, its something that the various countries are going to need, governments are going to need to assess and figure out the right involvement and path ahead. Important the International Component in all of this, in terms of getting help from asia for example. This is certainly challenging. I can tell you everyone from the malaysians, new zealand, japanese involved, chinese, everyone, all countries and all people involved are dedicated to putting best effort forward and trying to resolve.

You may be seated if you so wish. Thank you my lady. Yes mr. Roux. Thank you. Mr. Dickson, what are are your qualifications . I have a bachelor of science degree in chemistry and geology. Honors degree in geology and masters degree in geology. Post graduate Diploma Museum science. Those are my qualifications. Lets stop. When did you obtain those qualifications . My lady i may add it will be made available to court. It is not printed but well put the copy before you. I received masters 1998. And your first degree . I received that 1980. Which university . University of cape town. Now thats apart from your qualifications . I was at the Forensic Science laboratory 18 years. Of the South African Police service . South African Police service 1994 to end of 2012. During my time there i did many different courses in either instrumental crime scene examination, exhibits, identification, those sorts of courses. Locally as were nationally from fbi. There was reference at some state you worked together at the forensic. That is so. I was in charge of materials analysis subsection of which the colonel is now the head. Under that body i was in charge of all types of trace evidence, forensic geology, fibers, all types of organic pollutants, crime scene investigations which were varied such as industrial accidents or theft or break ins or break outs. Its a very wide gentlist area for those i think thises that dont fit into little boxes or big boxes. Most the people when i was in charge is there were the only person or maybe one of two with those specializations. It was diverse. At one stage it used to be called diverse analysis because of that my lady. Were you consulted by other members of the Forensic Department . Yes because my first specialization was as a geeoologist. That was why i was employed the first time by the South African Police service. They needed a geologist. I often received calls from outside when other members of the Forensic Science in the laboratory were on crime scenes. There was something geological, trace evidence of dirt or things. I would go to crime scenes to assist or within the organization within or area because its very difficult to work many isolation. You want to exchange ideas. People would come to me to discuss and i would go to them to discuss. How did your Work Experience start with ballistics . My experience of wound ballistics is minimal in the Practical Application what i know is what ive read and discussions with various members. But practically i apply basic sciences such as physics, chemistry and so on to understand the underlying causes. Im not a ballistic experts, not a dna expert, not a toxicologist. Im a more trace evidence which covers many of those fields and sometimes at a crime scene its not just one thing thats there. Evidence covers a diverse field and in the materials analysis subsection, our crime scenes and the cases we got were extremely diverse. Before today, have you ever given evidence in court . I have given evidence in court over the past 18 or more years. Not often, maybe three or four times a year because at the Forensic Science laboratory, you issue two one two statement which acts of fact. Were going to leave the court in pretoria. Theyre going through a series of defense witnesses now over the next couple of days. Possibly adjournment starting for easter week also. Well keep you on main evidence that comes to light in that pistorius trial. Weve seen the wrapping up of Oscar Pistorius testimony today. Judges at the International Tribune have dropped the charges. Theyre accused of having commanded the forces that killed 8,000 muslim men and boys in the town in 1995. Well be back with all our top stories in five minutes or so. Stay with us.
