Israeli teenagers: Netanyahu warns Hamas it will pay
Israeli PM says three boys were 'kidnapped and murdered in cold blood by human animals.. Satan has not yet invented vengeance for the blood of small child'
Israel has found the bodies of three missing teenagers, accusing Hamas of their murder and vowing to make the Islamist movement pay.
But a senior Hamas official warned Israel against any reprisals, saying it would open "the gates of hell".
The discovery of the three bodies in a field in the southern West Bank came 17 days after the youngsters disappeared, triggering a huge manhunt during which five Palestinians were killed and more than 400 arrested.
It also triggered a surge in rocket attacks against southern Israel by militants in the Gaza Strip, which triggered retaliatory Israeli air strikes almost nightly.
US President Barack Obama condemned the "senseless" murder, saying that as a father himself, he could not imagine the "indescribable pain that the parents of these teenage boys are experiencing."
He also urged "all parties to refrain from steps that could further destabilise the situation."
Israel has publicly blamed Hamas for the teenagers' abduction and staged a major crackdown on the Islamist movement's West Bank network.
But so far, the military has held back from attacking Hamas's power base in the Gaza Strip.
"This evening, we found three bodies and all the signs indicate that they are the bodies of our three kidnapped youngsters," Prime Minister Benjamin Netanyahu told ministers at the start of an emergency session of his security cabinet.
"They were kidnapped and murdered in cold blood by human animals.. Satan has not yet invented vengeance for the blood of small child," he said.
"Hamas is responsible and Hamas will pay."
The bodies were found in the southern West Bank near the town of Halhul, some 10 minutes from the roadside where they were last seen hitchhiking.
"During the search for Eyal Ifrach, Gilad Shaer and Naftali Frankel, the IDF discovered 3 bodies," the Israeli army said on Twitter.
Army spokesman Lieutenant Colonel Peter Lerner said the bodies had been discovered around 1400 GMT but he refused to comment on the cause of death.
"At around 5.00 pm, the IDF uncovered three bodies in the northwestern Hebron district," he told reporters, saying the bodies were being transferred for formal forensic identification.
"We have informed the families but final identification is pending."
One of the civilian volunteers involved in the search told army radio the bodies had been found under a pile of branches and stones in a remote area.
"Today, during a sweep with the army, one of the guys spotted something unusual, they started to move branches and stones and found the bodies," said volunteer Benny Truper.
"It was a very isolated area, more or less at the end of the world."
Shortly before the news was made public, Netanyahu convened a meeting of his security cabinet with ministers expected to take "operative" decisions, public radio said.
Deputy defence minister Danny Danon called for a widespread operation to "eradicate" the Islamist movement.
"We will not stop until Hamas is completely defeated," he said.
"The homes of the terrorists must be demolished and their arms caches destroyed."
Following the teenagers' disappearance, Israel launched a vast search and arrest operation, which also sought to lay waste to Hamas's West Bank network.
More than 400 Palestinians were arrested, two thirds of them Hamas members, and another five people killed in clashes sparked by the campaign, dubbed Operation Brother's Keeper.

But Hamas on Monday warned Israel against any punitive action against the Islamist movement.
"If the occupiers carry out an escalation or a war, they will open the gates of hell on themselves," Hamas spokesman Sami Abu Zuhri told AFP.
Hamas has dismissed the Israeli allegations as "stupid" with Abu Zuhri accusing Israel of fabricating the kidnapping as an excuse to crack down on it.
"The disappearance and murder of the three Israelis is only based on the Israeli narrative, and the occupation is trying to use this story to justify its extensive war against our people, against resistance and against Hamas," he charged.
President Mahmud Abbas convened an emergency meeting of the Palestinian leadership to discuss the latest developments.
Abbas has come under massive Israeli pressure to renounce a reconciliation agreement with Hamas under which a merged administration for the West Bank and Gaza was formed in early June for the first time in seven years.
British Prime Minister David Cameron condemned the killing of the three teenagers as an "inexcusable act of terror".
French President Francois Hollande hit at out at their "cowardly murder".
