UN Secretary-General Antonio Guterres has called for an independent investigation into deadly clashes in Gaza between Palestinians and Israeli troops.

Security Council members have urged restraint on both sides but they have not decided on any action or joint message after an emergency meeting.

Kuwait convened the talks hours after the bloodiest day in Gaza since the 2014 cross-border war between Israel and Hamas.

Sixteen people were killed and more than 750 wounded by Israeli fire as thousands of Palestinian protesters marched to Gaza's border with Israel, the Palestinian Health Ministry said.


The Israeli military said thousands of Palestinians threw stones and rolled burning tyres towards troops, that Palestinian gunmen fired towards soldiers and that militants were trying to conduct attacks under the cover of protests.

Guterres wants "an independent and transparent investigation" into the violence, spokesman Farhan Haq said.

Palestinian Ambassador Riyad Mansour said he was disappointed the Security Council did not unite to condemn what he called a "heinous massacre" of peaceful demonstrators, or to support his call to provide protection for Palestinian civilians.

"We expect the Security Council to shoulder its responsibility" and "defuse this volatile situation, which clearly constitutes a threat to international peace and security," Mansour said.

Israeli Ambassador Danny Danon said "the international community must not be deceived" by what he termed "a well-organised and violent terror-gathering" under the banner of a peaceful march.

"The Palestinians sunk to a new deceitful low so that they could use the UN to spread lies about Israel" while its representatives were not there because of the Passover holiday, Danon said.

Some Security Council members suggested an investigation and emphasised that Israel should ensure force is only used proportionally. They all expressed alarm at the flare-up of conflict in a volatile region.

The US, which often complains about what it sees as anti-Israel bias at the UN, urged all involved in the conflict to lower tensions.


Russia and China, meanwhile, emphasised a need to step up diplomatic efforts towards resolving the Israeli-Palestinian conflict as a whole. Israel and Hamas have fought three cross-border wars in recent years.

The protests come as Gaza is in the 10th year of a border closure. Israel and Egypt imposed the blockade after Hamas seized Gaza from forces loyal to the militants' rival, Palestinian President Mahmoud Abbas, in 2007.
