Qatar's Emir Sheikh Tamim bin Hamad Al Thani on Tuesday called on the UN Security Council to push Israel to return to the negotiating table over the war in Gaza.
Speaking at the 44th Gulf Cooperation Council (GCC) summit in Doha, Sheikh Tamim urged the international community to do more to "end the heinous crime that has continued for nearly two months".
"We are constantly working to renew (the truce) and to alleviate the burden of our people in the Gaza Strip, but truces are not an alternative for a comprehensive ceasefire," he said.
Qatar, which has been leading negotiations between Hamas and Israel, had earlier secured a seven-day truce, along with Egypt and the US, that saw the release of a number of hostages and Palestinian prisioners and the flow of humanitarian aid into Gaza.
In November, the 15-member UN Security Council overcame an impasse and called for urgent and extended humanitarian pauses in fighting between Israel and Hamas for a "sufficient number of days" to allow aid access.
Israel launched its assault on Hamas in retaliation for an October 7 cross-border attack.
An Israeli airstrike killed at least 26 Palestinians, including children, in a house in Shejaia in Gaza City, local health authorities said on Wednesday.
President Volodymyr Zelenskyy said that Ukrainian forces had captured two Chinese men fighting for Russia in eastern Ukraine, potentially threatening a fragile peace effort in the three-year-old war.
As calls for Lebanon's Hezbollah to disarm gain momentum, a senior Hezbollah official told Reuters the group is ready to hold talks with the Lebanese president about its weapons if Israel withdraws from south Lebanon and stops its strikes.
Russian forces staged huge drone attacks on eastern Ukraine late on Tuesday, triggering fires and injuring at least 22 people, regional officials said.
United Nations Secretary-General Antonio Guterres has rejected a new Israeli proposal to control aid deliveries in Gaza, saying it risks "further controlling and callously limiting aid down to the last calorie and grain of flour".
