An emergency meeting of Arab and Islamic states is taking place in Qatar in response to Israel's air strike on Hamas leaders in Doha last week.
A draft resolution seen by the Reuters news agency condemns what it calls Israel's 'hostile acts including genocide, ethnic cleansing, [and] starvation', which it says threatens 'prospects of peace and coexistence'. Israel has strongly denied such allegations.
It is not clear what practical decisions could be taken, as analysts say any kind of military response is out of the question.
Earlier, Qatari Prime Minister Mohammed bin Abdulrahman bin Jassim al-Thani urged the international community to stop applying 'double standards' and to punish Israel.
On Sunday, US President Donald Trump said that 'Qatar has been a very great ally. Israel and everybody else, we have to be careful. When we attack people we have to be careful.'
Departing for Israel, US Secretary of State Marco Rubio noted that Trump 'didn't like the way [the Qatar attack] went down'. During his visit, Rubio will meet Israeli leaders to discuss the ongoing war in the Gaza Strip and other issues affecting the Middle East.
The Israeli strike on Qatar's capital was condemned by the UN Security Council, which emphasized the importance of de-escalation and expressed solidarity with Qatar.
Israel defended its actions, stating that the strike was necessary to 'remove some of the people if they are not willing to get a deal' to end the war. Hamas confirmed the survival of its negotiating team but acknowledged the loss of five members.
Qatar has played a key role in diplomacy surrounding the war, serving as a mediator in negotiations between Hamas and Israel.
