David Cameron has urged Israel to pursue a peace deal with Palestinians that could mean "an end of all conflict" in the Middle East.
Israel says it has has intercepted a "monstrous cargo" of weapons on a cargo ship heading to Gaza from Iran.
ITV News Correspondent Geraint Vincent explains why Israel's alleged attack at the Lebanese-Syria border may not create new conflict.
ITV News' Political Editor Tom Bradby is with David Cameron as he addresses Israeli MPs in the Knesset:
'With me, you have a PM whose belief in Israel is unbreakable,' Cameron says.
'Delegitimising the State of Israel is wrong. It is abhorrent,' he says. 'And together we will defeat it.'
Cameron is being pretty trenchant here in his support for Israel.
Prime Minister David Cameron reiterated his support for a two state solution for Israel and Palestine during a two-day visit to Israel and the Palestinian territories.
Speaking ahead of his two-day visit to Israel today, David Cameron said that if the leaders of Israel and the Palestinian Authority could take the final "difficult steps" to a peace deal "the prize could be great".
– Prime Minister David Cameron
I want to encourage Prime Minister Netanyahu and President Abbas to build on the strong leadership they have shown so far and to take the final difficult steps towards peace.
The prize could be great: a stable, prosperous Middle East with a sovereign and viable Palestinian State living in peace alongside a secure Israel at the heart of it.
A secure future. A prosperous future. That's what we should all set our sights on.
David Cameron has called on the leaders of Israel and the Palestinian Authority to "take the final difficult steps towards peace," as he prepares to fly to Israel this morning on what will be his first visit to the region as Prime Minister.
Mr Cameron will join US Secretary of State John Kerry in trying to persuade Israeli Prime Minister Benjamin Netanyahu and Palestinian President Mahmoud Abbas to agree to an outline for a final peace deal by the end of April.
Before his two-day visit to Israel and the Palestinian territories, he said: "Secretary Kerry's efforts to secure agreement on a negotiating framework that could lead to peace are entering a critical phase and I'll be using my visit to support those peace efforts."
David Cameron will hold talks with Middle East leaders when he visits Israel and the Palestinian territories this week.
The prime minister will meet Israeli counterpart Benjamin Netanyahu and deliver a keynote speech to the Knesset, the country's parliament, after arriving in the area on Wednesday.
He will also discuss the situation with Palestinian leader Mahmoud Abbas during his two-day trip.
David Cameron will visit Israel and the Palestinian territories on Wednesday, in what will be the prime minister's first visit to Israel since entering Downing Street.
He was due to travel to the area last month, but the trip was put off as winter storms battered Britain.
There had been speculation he may be forced to postpone again due to a strike by workers at the Israeli Foreign Ministry.
The Israeli army says it has seized a large shipment of munitions being sent from Iran to Palestinian groups on the Gaza Strip.
An Israeli Defence Forces Twitter account shared the following images:
The Arab League endorsed Palestinian President Mahmoud Abbas's rejection of Israel's demand for recognition as a Jewish state, as U.S.-backed peace talks approach a deadline next month.
The US want Mr Abbas to make the concession as part of efforts to reach a "framework agreement" and extend the talks aimed at settling the Israeli-Palestinian conflict.
Benjamin Netanyahu has been Israel's first prime minister to make recognition of his country as a Jewish state a requirement for peace.
