Thousands gathered around Modein cemetery, as the BBC's Yolande Knell reports
The
funerals of three teenagers who were abducted and murdered while
hitch-hiking in the occupied West Bank have been held in Israel.
Addressing thousands of mourners, PM Benjamin Netanyahu described their killers as "heinous murderers".Israel has blamed the Palestinian militant group Hamas for the deaths. Hamas has denied any involvement.
The youths' bodies were found on Monday evening, more than two weeks after the trio went missing.
Mr Netanyahu has said Hamas will be made to pay a price for the killings.
Speaking at the joint funeral held for Naftali Frenkel, Gilad Shaar and Eyal Yifrach in central Israel, Mr Netanyahu said "a broad moral gulf separates us from our enemy. They sanctify death, we sanctify life".
The funeral took place at Modein cemetery in central Israel. Modein, which is between Tel Aviv and Jerusalem, is close to the boys' family homes.

The scenes at the funeral of the three murdered teenagers were extraordinary.
In burning afternoon sunshine, tens of thousands of mourners made their way through the steep, arid landscape outside the central Israeli town of Modein to this tiny hilltop cemetery.
The crowds were large enough to delay the start of proceedings.
When the funeral began, the Israeli Prime Minister Benjamin Netanyahu was among the speakers - although there were reports that the families had asked him not to address the issue of any possible Israeli response to Hamas.
Mr Netanyahu saw a lesson in the tragedy that resonates for him with broader Jewish history.
"One nation stood together," he said, "and got a reminder of who we are and why we are here."
As day gave way to night here on both sides of the Palestinian-Israeli divide, the question of how Israel will respond to this bitter loss was being asked with greater urgency.
The teenagers' bodies were found under a pile of rocks near the
Palestinian town of Halhul. An Israeli official said it appeared the
youths had been shot soon after their abduction.
Israeli troops flooded into Halhul after the discovery.

Palestinian witnesses said Abu Aisheh's home was destroyed.
Israeli security forces have set up blockades and closed down whole areas around Halhul, a few kilometres from where the teenagers were last seen.
Palestinian Authority President Mahmoud Abbas called an emergency meeting of the Palestinian leadership and has expressed "regret" over the deaths.
More than 400 Palestinians were arrested, while five were killed in fighting with Israeli troops.
Mr Netanyahu has said the incident is a consequence of "the partnership" between Hamas, which rejects Israel's right to exist, and the Fatah movement of Mr Abbas.
The two signed a reconciliation deal in April after years of division and formed a unity government last month.
