Days of intense violence. Inside gaza, it looks every bit as if palestinians are feeling the full force of Israeli Military power. Israel says hamas is responsible for the suffering of gazas civilians. And its retaliation for the hamas attack is only just begun. Hamas has threatened to start killing its israeli hostages. The air strikes rolled on, hour after hour. Palestinian armed groups, undeterred, kept up their own barrage of israel. 0ur bbc team was in ashkelon in southern israel, not far from the gaza border when a salvo came in. Ashkelon is so close to gaza that there is no more than a ten second warning. Israel is moving in more fire power. The next stage of the offensive against hamas looks certain to be a Ground Offensive, much bigger than other incursions since hamas took over in gaza in 2007. Lines of cars outside a Military Base on the road to gaza were parked by reservists as they reported for duty, getting ready, saying their goodbyes. Parents came to the base for a few minutes with their sons. We are praying and hope for the best. Amidst tough times now. And we are telling him to try and concentrate on his mission, without thinking too much about other friends that got injured or killed. Israels Prime MinisterBenjamin Netanyahu broadcast to his nation. Translation he said hamas has made a mistake of historic proportions. We will, he said, be exacting a price that we be remembered by them and other enemies for decades. And now israelis are waiting for the government and army to act. Sderot, the israeli town close to gaza littered with the debut with the debris of war felt like the essence of israels trauma, almost deserted except for forces. Hamas has rocketed sderot for years but has never before stormed in. At the centre of the hamas Killing Ground was the police station. They broke in and used it as a fire base to shoot civilians as well as soldiers. Blood from israels dead and wounded smears the walls. Even here in what is always a front line town, for israelis, this was not supposed to happen. They expected their military, backed up by the intelligence services, to protect them. And the fact that that didnt happen means recriminations about who might be responsible have already started. But at the same time there is a strong sense of national unity, with a country under attack, about what happens next. In the places that hamas attacked Israeli Military as well as the few civilians left are jumpy, still shocked. A Ground Offensive didnt feel imminent. And in gaza, a few miles away, casualties come into the main hospital. The first few hundred of many more. It will get worse. Palestinians and israelis once more caught on the anvil of war in a conflict a century old that is as deadly it has ever been. Jeremy bowen, bbc news, ashkelon. Getting into gaza is incredibly difficult and dangerous. My colleague, rushdi aboualouf, is there now. Its not safe for him to broadcast live at the moment, so he sent this update. This is by far the biggest ever israeli air strikes in gaza, on this scale, in this intensity. This is the biggest. In this building, its a Seven Storey Building where 20 to 30 families, they live in this building. I could hear the screaming of the kids, they were shouting. In the background, if you can see, its totally black. Most of the Electricity Supplies in gaza are not functioning, internet is down in every corner of this city. Talking about the humanitarian situation, gaza has been suffering for three days without electricity. The crossings, most of the crossings are closed except the rafah crossing with egypt, and it only allows people to go in and out no goods. No fuel is coming, no medicine for hospitals. The Health Ministry issued a Statement Today warning that within 48 hours the essential medical supplies are running out in the hospital. Nearby explosion and they need urgent supplies to be able to provide services to many people. I could hear in the background israeli fighter jets are still flying overhead and targeting places between time to time and it seems that this night, the palestinians in gaza have never seen before. Raphael poch, who is a spokesperson for united hatzalah, israels National Volunteer ems organisation, told me about the situation there. It has been chaos which has been later turned into organisation and balance. Saturday morning we were all awoken around half past six in the morning with the attacks starting in the Gaza Periphery, then the Rocket Barrages through central israel, and the jerusalem corridor, expanding further north as well. As the rockets were fired at Israel Hundreds of people were killed, captured, kidnapped, atrocities and horrors is really what we were facing at the beginning. A number of our volunteers were even injured, one was killed while trying to save lives of other people who were injured, they were killed by her Master Terrorists who penetrated into israel. Very quickly we organised a number of our organisation, 7000 volunteers in israel who dropped what they were doing whatever there is emergency, they respond in less than three minutes, medical emergencies. We are used to dropping whatever were doing and responding to emergencies at hand and we have brought in 1500 volunteers from across the country to the Gaza Periphery to provide relief and humanitarian medical services, to civilian and Military Personnel who are injured in the attacks. Thats been ongoing, continuing since saturday morning and our teams are still there, bringing new volunteers to replace them who are tired who want to go home. And they returned a couple of hours later to continue to provide treatment. Weve set up medical clinics in the periphery, transported patients out, so far we have treated over 1500 people. We have transported them by helicopter and ambulances. After stabilising them on the field, transported to skittles in central and Southern Europe as well, wherever they could be taken. We are doing everything we can, sometimes going to home and homes and towns were people are told not to leave or as of the houses because it is too dangerous, bring food, water and medical supplies. Dangerous, bring food, water and medicalsupplies. Its dangerous, bring food, water and medical supplies. Its a bit of whats going on here. There is the home front facing continuous Rocket Barrages, we had a siren a few hours ago, a rocket unfortunately landed in the town next to us and we had to go to respond that were number of people were injured. It is a continuing conflict and unfortunately it seems like its only escalating at this point. We are doing the best we can to provide humanitarian aid and medical service to everyone who needs it. Who needs it. You see is an ongoing who needs it. You see is an ongoing conflict who needs it. You see is an ongoing conflict and who needs it. You see is an ongoing conflict and it who needs it. You see is an ongoing conflict and it is, i who needs it. You see is an ongoing conflict and it is, a | ongoing conflict and it is, a situation which is rapidly unfolding as we track it. How are you preparing for the potential of a longer conflict as that is the prime apprehension at the moment . How first needs are apprehension at the moment . Hm first needs are really purchasing more medical equipment. We run out of a lot of reserves already in the first couple of days of the conflict because of the massive amount of people we have to treat. In addition to the regular medical Emergency Response across the country, so we are having a campaign with people and support us, by our website, rescueisrael. Org. This is a non domination, we are treating jews, muslims, christians, everyone in israel who needs it and we have volunteers from all the nominations as well and we are working to save lives so the better equipment we have, the better equipment we have, the better we can help the populace and the injured and get them to hospital as quickly as possible, and them more lives we can say. As weve heard, hamas warned on monday night that it will start executing Israeli Citizens held captive much of the activity has centred around ashkelon at the border with gaza where anna foster sent this report.

Forthe it will kill someone held captive. For the families desperate for news, fears are growing. Yolande knell, bbc news, tel aviv. A major Focus A Majorfocus on a major focus on the ground is how and whether israel will undertake a Ground Offensive with the Prime Minister promising to use enormous force, and hamas warning it could kill the more than hundred hostages left. So how might Israeli Forces be planning for a long large scale operation . We have the former deputy chief of the top Special Forces unit in israel and he joins us live from miami. Thank you for your time on newsday. As a former commando in the Israeli Special forces, former commando in the Israeli Specialforces, you have Special Forces, you have undertaken specialforces, you have undertaken many difficult musicians, many still classified of course but you did for example lead the assault team to rescue hostages held on a bus in the 1980s was the powder is the challenge here for Israeli Special forces compared to previous incidents . Thank you for having me, and thank you for covering this Human Tragedy over the day. So what is probably not clear to the audience is that, in military affairs, there are different types of battle. You quite differently in urban territory, in a forest, in the desert, and hostage rescues are completely different mode of battle, whereby the priorities are very different. Typically, the whole idea is to accomplish your goal while maintaining the integrity of yourforce. Your goal while maintaining the integrity of your force. In other words, integrity of your force. In otherwords, Making Integrity of your force. In other words, making sure that your people are not heard. When your people are not heard. When you are going to rescue hostages, what becomes the number one priority is rescuing the hostages. At a great sacrifice for the force that is supposed to free the hostages. And if you get into the details of that, that basically changes the whole setup of th
