Qatar's prime minister denounced Israel on Sunday as foreign ministers from Arab and Muslim nations met to discuss a possible unified response to Israel's attack on Doha targeting the leadership of the militant group Hamas.

"It is time for the international community to stop applying double standards and punish Israel for all the crimes it has committed," Sheikh Mohammed bin Abdulrahman Al Thani said.

He said Israel's attack on Doha showed its "continued violation of international law, human values, and diplomatic norms".

Sheikh Mohammed, who also serves as Qatar's foreign minister, made the comments before a meeting on Monday of leaders from those nations.

Sheikh Mohammed said Qatar remained committed to working with Egypt and the US to reach a ceasefire in the Israel-Hamas war that has devastated the Gaza Strip after Hamas' attack on southern Israel on Oct. 7, 2023.

However, he said that the Israeli strike that killed six people - five members of Hamas and a local Qatari security force member - represented "state terrorism."

Sheikh Mohammed stressed the moment had come for consequences to Israel's attacks in the wider Middle East.

There was no immediate response from Israel, which is hosting US Secretary of State Marco Rubio this weekend.

But Israeli Prime Minister Benjamin Netanyahu on Saturday night again defended the strike.

Qatar, an energy-rich nation on the Arabian Peninsula that hosted the 2022 World Cup, long has served as an intermediary in conflicts.

For years, it has hosted Hamas' political leadership at the request of the US, providing a channel for Israel to negotiate with the militant group that has controlled Gaza for years.

But as the Israel-Hamas war has raged on, Qatar increasingly has been criticized by hard-liners within Netanyahu's government.

Netanyahu himself has vowed to strike all those who organized the Oct. 7 attack, and in the time since the attack on Qatar has doubled down on saying Qatar remains a possible target if Hamas leaders are there.

Netanyahu faces increasing pressure from the Israeli public over the fate of the remaining hostage held in Gaza.

There are still 48 hostages remaining in Gaza, of whom 20 Israel believes are still alive.

Israel's war on Gaza has killed more than 64,000 Palestinians, according to local health officials, who do not say how many were civilians or combatants.

It says around half of those killed were women and children.
