Israeli tanks have moved along the border with lebanon as Tension Mounts between israel and lebanons powerful armed group hezbollah. The Israeli Military says it fired artillery into an area of lebanon where cross border fire was launched. 0ur middle east correspondent Quentin Somerville is in kfarchouba on lebanons border with southern israel and has sent this update. This morning hezbollah targeted the israeli position behind me on the hill bear, a radar station, firing a number of mortars and artillery back. It released a statement afterwards saying the attack was in solidarity with the palestinians. It was also very narrow and calibrated attack. Because hezbollah is one of the most effective militant organisations in the middle east, it has a huge arsenal of resources. It can strike deep into israel. This was a very calibrated attack, very carefully positioned. Not to lead to escalation, at least at this moment, and since then, we have heard from senior hezbollah official that they will not be neutral in the war. They said the United States and israel must stop or the whole region will become involved. What we know from israel, they are not planning to start because israel is planning what it says will be a long war. A threat, really, ora spoken what it says will be a long war. A threat, really, or a spoken threat from hezbollah that there is a risk of them becoming further enrolled in the conflict with the enormous arsenal that they have if this conflict continues to escalate. find conflict continues to escalate. And the question. Conflict continues to escalate. And the question. I conflict continues to escalate. And the question, i guess, many are asking is, you know, how moore is hezbollah capable of doing in terms of damage . fix, hezbollah capable of doing in terms of damaue . �. ,. , of damage . A great deal, if it comes to that. Of damage . A great deal, if it comes to that they of damage . A great deal, if it comes to that. They have. Of damage . A great deal, if it comes to that. They have. We of damage . A great deal, if it comes to that. They have. We know of damage . A great deal, if it comes to that. They have. We know that l to that. They have. We know that they have a great significant supply of long range missiles, notjust of long range missiles, not just here of long range missiles, notjust here at the border, notjust a small israeli radar station, but deep inside israel. Of course, israel will respond. I am, about 55 minutes ago, israel responded and there was an Artillery Strike here on the border of the village. All day, we have heard israeli warplanes and drones in the area, that is not unusualfor drones in the area, that is not unusual for this part of Southern Lebanon, you often hear them here, but certainly an escalation and intention under dissipation. That can be felt here and all over the country. A worry that this country, already deeply troubled, in the middle of a financial crisis, without a president , desperately poor and has a war on the economic crisis will fate yet another issue. That was Quentin Somerville there on the border between lebanon and israel. A little earlier, we brought you sad news, the death of a british man by the attack of hamas. Nathanial young has died.

I want to show you some of the latest videos that been coming into us and our bbc verify team have identified.

It explaining how they went about checking this video, and working out where and when it was taken. The video this is an incredible moment, the moment was filmed right next to the bbc offices in gaza. As you can see, a building being flattened by an israeli missile strike. The roof you are looking at this from as bbc office. It was destroyed very close to the bbc� s broadcast position in gaza. The footage was filmed on saturday, as israel began retaliatory strikes following the unprecdented attack by palestinian militants. A video has been released by the Palestinian Militant Group hamas storming the erez Military Site North of the gaza strip. Shouting. The alqassam brigade the Military Wing of hamas released footage of an assault on the Erez Beit Hanoun crossing between israel and gaza. The attack was carried out on saturday morning. Let me just bring you these pictures from gaza. Where a mosque in khan younis is among buildings damaged. This is Al Ameen Mosque which was hit in an israeli strike this morning. There are copies of the koran scattered on the ground. Dan darlington is reported as missing in israel by his family. He lives in berlin but was in israel visiting friends. The Communications Network is down and his family havent spoken to him for 24 hours. This is a picture of dan. His half sister inbal spoke to him at 8. 30 on saturday. Dan was with a friend. His family know that his girlfriend took his gun out to fight, got hurt but survived. I spoke to our reporter in gaza Rushdi Abualouf a short while ago. I asked him what he knew about the warnings to citizens in gaza to leave their homes. Yeah. We know that many families started to move. But in the last 10 minutes, about 5 to 6 airstrikes just hit the area where the israelis warned residents to leave. And thats, as we expected, the israeli air raid intensify in this area. The israeli army issued a small video directing people to leave this area and go to the city center. And they said we are going to attack hamas, a terrorist group that is attacking israel. Since last night, when israel launched this, a Retaliation Operation in gaza, many areas people were leaving. And we understand from sources in the un that as many as 22,000 people already left their homes and now they are taking shelter in a un school. We have seen this scenario before as gaza fought like four wars or hamas fought four wars with israel in the last 17 years. And gaza, the people in gaza, they dont have any shelter facilities. So people usually what they do, they go to the un school because they believe that you are in a school, is protected by the un. And nobody will hit them there. Also, we noticed that people are going to hospitals for the same reason. Since last night, until now, we understand from security sources that about 280 targets have been hit by israel. Most of them belong to hamas militants. They had tanks, they had military facilities, military infrastructure, even some police checkpoints, some police stations. A hamas bank was hit. Buildings, high buildings were hit this morning. I have been in the Gaza City Center where like 11 Storey Building was completely destroyed and razed to the ground. The main road for the Gaza Downtown was closed for about two or 3 hours. And the situation, the humanitarian situation seems to be getting worse and worse with the israel cutting 80 of the Electricity Supplies into gaza. And already most of the Internet Lines are not working since yesterday. Whats the feeling now amongst people who are in gaza who are trying to find shelter . How much fear is there of more to come from israel . Yes, of course. I mean, people have a mixed feeling about whats going on. Yesterday, there was some sense ofjoy. People were like celebrating, praising hamas fighters who in there, who the palestinians, majority of the palestinian in gaza believed that they were revenge by israel. The israeli action in the west bank, in Al Aqsa Mosque and also in gaza, they were like welcoming what hamas did. But in the other hand, today they started to feel the reality that its a war. And war, people in this poor, Densely Populated place, they knew well what what war would mean for them. Back in 2014, there was a war for about 50 days. And now with the Electricity Supplies not working, internet, israel shut all of the border around gaza and there is a fear of very soon we will have some sort of serious humanitarian crisis a food and medicine and electricity, like dont come to this 2. 3 Million People here. Yes. Live pictures now coming into us from gaza city. We can see huge plume of smoke, it looks like some sort of building has been hit by the Israeli Defence forces a minute to go.

We also know from the abyssinian Health Authorities the palestinian Health Authorities that hundreds have been killed. There is the latest air strike from another album. This could be from the hospital. They havent had this completely verified, but we are hearing from various reports that this could be the latest strike from the idf and could be near a hospital in gaza city.

An israeli man, thought to be her partner, is also seized by palestinian militants. The pair had been at an outdoor Music Festival near the gaza border. Other video shows partygoers fleeing across the desert. Some try to get into cars and others flee on foot. There are reports that they were attacked by a number of hamas militants that one eyewitness described as shooting people indiscriminately. A short time ago, i spoke to amit parpara from tel aviv.
