Ifill still to come on the newshour the group and the motives behind the deadly Easter Sunday bombing in pakistan. A fight to push back isis in northern iraq. Our politics monday team on the week ahead on the campaign trail, and much more. Woodruff in pakistan, the mosul was overrun nearly two years ago and has become a vital hub for the groups operations in iraq. But whether iraqs military is up to the challenge is an open question. Even as the potential grows for deeper american involvement. Special correspondent Jane Ferguson reports from special correspondent Jane Ferguson reports from the frontlines, near makhmour, iraq. Reporter in an effort to soften isis positions, iraqi forces bombard them repeatedly. They are trying to push forward from this sandbank, up the hill to a village Islamic State fighters are dug into. Last week, the Iraqi Army Suddenly announced the launch of the longawaited battle for mosul city. In reality, so far just several villages have been retaken in the makhmour area, well south of mosul. This is as far as the front line comes for these iraqi troops. They are mortaring the village in that direction that is just on that hill. Thats where isis positions are. That village is called al nasr. They plan to then move in and try to occupy the village but they have been trying to do that for three days. Far beyond that village is the city of mosul, and bitbybit, inchbyinch, they plan to re take it. So far, progress is slow. Iraqi forces swiftly abandoned their positions here in 2014, when isis swept across the country. Morale in the military has yet to fully recover. So, when iraqs commander of ground forces, Major General riyadh jalal tawfig, showed up near the front lines in an unexpected visit, there was great fanfare. But he didnt wish to talk about past mistakes. When isis took Mosul Iraqi Forces quickly withdrew from the city when isis were moving quickly. How do you feel you can prevent that from happening again . translated these issues depend on the timeframes and plans designed for them. After that, for every incident there will be a response, if god wills it. We will retake mosul. Reporter the battle lines in iraq are as complex as the countrys woven identities. Iraqi forces are holding this ground alongside kurdish fighters called peshmerga. They are a skilled fighting force, protecting the semi autonomous kurdish region, which borders mosul. They are holding the line on both ends of the iraqi army. Peshmerga fighters are supported by u. S. Air strikes when they confront isis, but are not given the extensive military equipment the official iraqi army receives from america. This peshmerga commander, colonel naji bedaroni, wandered over to inspect their progress. He was not impressed translated the operation is very weak. Its not strong enough. I believe that if the peshmerga had the equipment they have we could liberate this village in 3 to 4 hours. Not 3 to 4 days. Reporter Kurdish Forces have pushed isis out of most of their areas. An agreement for them to take part in the battle for mosul, a mostly arab city, has yet to be reached. But without the peshmerga, the iraqi army will struggle to retake the city alone. Are the peshmerga taking part in this fight . translated for this we need a political decision. That area that is being targeted for this operation is not a kurdish area. We are just guarding our bunkers. If we get orders, for sure we can do that but until now we have no gotten any orders. Reporter how is the relationship between the Kurdish Peshmerga fighters and the iraqi army . translated we are coordinating with them, we are helping them. But they are weak, they dont believe strongly in the cause. Reporter soon we are on the move, to another part of the battle field. Unseen on this frontline, but still playing a major role, are u. S. Forces, providing advise and assist support for iraqi and Kurdish Forces. An American Marine was killed earlier this month just a few days after arriving at a base in here in makhmour. Only after his death did the u. S. Military announce the presence of the marines. The chairman of the joint chiefs of staff, general dunford, admitted last week there will be more u. S. Boots on the ground soon. We have a series of recommendations that we will be discussing with the president in the coming weeks to further enable our support for the Iraqi Security forces. The secretary and i both believe there will be an increase to the u. S. Forces in iraq in the coming weeks but that decision hasnt been made. Reporter the u. S. Military in makhmour declined requests from pbs for an interview. Fighting between isis and the iraqi army and Kurdish Forces has flattened village after village here. The scenes are of complete devastation. Civilians are running from their homes where the fresh fighting has broken out. These people came from the villages recently retaken from isis, seizing the chance to escape the fighting. Weve just come upon this scene here of civilians fleeing the frontline. Further back there, as far as the eye can see, where cars are coming from, there are several villages where isis have either retreated or have been pushed out by iraqi forces. Civilians are fleeing while they can, anticipating perhaps more maneuvers. Not everyone is jubilant. Traumatized and exhausted, these women and children arrived at another frontline position while we were filming. They ran from their village as isis retreated. A girl was killed. We are told isis shot her as she ran away. This elderly woman said they were being held as human shields they were wearing explosive belts and we couldnt leave because of them, she cries. Where are the men . Where are your men . translated they took seven from my family. Reporter this outpost is manned by another group involved in this offensive, hashd al shaabi, or Popular Resistance committees. They are militia, and quickly descend into fighting with the official Army Commanders accompanying us. We are told to leave. On this battlefield, its not always clear whos in on this battlefield, it is not always clear who is in charge. The fight to take back mosul from isis will be the toughest yet. Loosing the city could be a deadly blow for the terror group. Given the chaos of this battles earliest stages, a quick victory seems out of reach. For the pbs newshour, im Jane Ferguson in makhmour, iraq. Woodruff in pakistan, the government and people were reeling from yesterdays terrorist attack in lahore, the countrys cultural capital. The crime scene was strung with police tape and emptied of visitors this morning, while investigators searched for evidence. Sundays suicide bomber targeted christians at an easter celebration. But most of the dead were muslims whod been enjoying the park on a weekend. translated i was standing there near the seesaw when the blast occurred. The explosion was very loud. As we rushed over here we saw a pool of blood and people lying here and there. Woodruff a breakaway taliban faction claimed responsibility, its fifth attack since december. In a challenge to the government, the militants said in a statement we have entered lahore. The eastern city in punjab province, the countrys richest and most populous, is a power base of Prime Minister nawaz sharif. His government launched a paramilitary crackdown in punjab today. And, after visiting the wounded, sharif returned to islamabad, vowing to defeat what he called the extremist mindset. translated we will not let them raise their heads again, we will not allow them to play the lives of the people of pakistan. This is my resolve, this is my governments resolve and this is woodruff but in the capital, islamabad, muslim extremists rioted outside parliament for a second day. They chanted death to nawaz and demanded authorities impose islamic sharia law. Back in lahore, funerals played out all day as victims, including some of the children, were laid to rest. translated these people were innocent. They had no idea when they left their homes what was going to happen to them, terrorists killed these innocent people. We demand strict punishment for woodruff and at the vatican, pope francis called the attacks vile and senseless. We explore the situation in pakistan now with husain haqqani, who was pakistans ambassador to washington from 2008 to 2011. Hes now director for south and central asia at the hudson institute. Hes also the author of pakistan between mosque and military. And pamela constable, who has covered pakistan for the washington post, and is the author of playing with fire pakistan at war with itself. And we welcome both of you back to the program. Mr. Ambassador, let me start with you. This group, who are they ant where do they come from . Its a group part of the Pakistani Taliban, the t. T. P. , an affiliation with al quaida. They are an offshoot of the t. T. P. , they have flirted with supporting i. S. I. S. Recently aud have been responsible for other actions including a kidnappings for ransom and terrorist acts in the past. Reporter when you say they flirted with i. S. I. S. , what do you mean. They issued a statement saying we agree with i. S. I. S. s objectives but did go to far as to disassociated with al quaida and affiliate with i. S. I. S. Woodruff pamela constable, what would you add to that . Help us figure out how they fit into what we already know about the taliban and i. S. I. S. In this part of the world. Its interesting because, of course, the Pakistani Taliban has always been ferocious and antiwestern and very antistate, but this group seems to have been even more hard line. They split off from the Pakistan Taliban because it wasnt hard enough on sharia law and fundamentalist values and the leader of this group is from the border tribal area up in the northwest, but the fact that theyre focusing on punjab is extremely interesting and a major challenge for this government, unlike anything before. Woodruff why is that significant they went after punjab and significant lahore . Partly because as the tape mentioned, this is the power base of the government, but its also because punjab has always been a little bit offlimits in terms of the antiterror fight. There are some groups based in punjab that have government support, whether its acknowledged or not, theyve gone very lightly on them, theyve tried to appease them and now it really is coming back to haunt them because you have much more radical groups coming in and building on that foundation. Woodruff so why is punjab and lahore such a target . Lahore is only a target yesterday, but the fact remains that the rest of the country has been a target for much longer. The real problem lies in that attitude of the government of trying to protect the punjab while going to after terrorists in other parts of the country but not punjab and thats come bag to bite them. The fact is the Pakistani Military and civil leadership easily gets distracted by dilution of fighting india and influence in afghanistan and allowing
