The UN secretary general, António Guterres, has called for an independent investigation into deadly clashes in Gaza between Palestinians and Israeli troops, while security council members urged restraint on both sides.

The council did not decide on any action or joint message after an emergency meeting on Friday evening. Kuwait convened it hours after the bloodiest day in Gaza since the 2014 cross-border war between Israel and Hamas, the Islamist militant group that rules the coastal strip.

Fifteen 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 tires toward troops, Palestinian gunmen fired toward soldiers in one incident and 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.

The Palestinian ambassador, Riyad Mansour, said he was disappointed the security council did not coalesce to condemn what he called a “heinous massacre” of peaceful demonstrators, or to support his call to provide protection for Palestinian civilians.

He said the Palestinians “expect the security council to shoulder its responsibility” and “defuse this volatile situation, which clearly constitutes a threat to international peace and security”.

The 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.

He said “the Palestinians sunk to a new deceitful low so that they could use the UN to spread lies about Israel” while its representatives weren’t there because of the Passover holiday.

Some security council members suggested an investigation should be conducted and emphasised that Israel should ensure force is only used proportionally. Some also made noted Israel’s security concerns and called on demonstrators to avoid violence. They all expressed alarm at the flare-up of conflict in the volatile region.

“The situation is extremely worrisome,” said the Swedish deputy ambassador, Carl Skau. Equatorial Guinea’s ambassador, Anatolio Ndong Mba, warned that continuing violence could “escalate out of control and could further imperil what is already a very delicate situation” in Gaza.

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.

“Bad actors who use protests as a cover to incite violence endanger innocent lives,” said Walter Miller, an adviser at Washington’s UN mission.

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

Israel and Egypt imposed the blockade of Gaza after Hamas seized the strip from forces loyal to the Palestinian president, Mahmoud Abbas, in 2007.
