Kurdish security forces in northeast Syria said an Islamic State group attack killed three personnel on Sunday, as the jihadists keep up their attacks in Kurdish-controlled areas of the war-torn country.

Noting "escalating activity" by the jihadists, a statement from the Asayish security forces said an IS cell "targeted a patrol" from the force's convoy and road security department on the Raqa-Hasakeh road.

Israel has continued to strike Lebanon despite a November ceasefire that ended more than a year of conflict -- including two months of open war -- with militant group Hezbollah, which emerged severely weakened.

Lebanon's health ministry has said that Israeli strikes on the country's south killed two people, as the Israeli army said it targeted Hezbollah members in the latest raids despite a ceasefire.

Ukrainian President Volodymyr Zelensky arrived Monday in Vilnius for a summit with the leaders of NATO's eastern and Nordic members, some of Kyiv's staunchest backers amid the Russian invasion.

Gaza's civil defense agency said Israeli fire killed at least 22 people on Sunday near a U.S.-backed aid distribution center in the southern city of Rafah, revising an earlier death toll.

Hamas announced that it has replied to a U.S.-backed Gaza ceasefire proposal, but Washington's main negotiator criticized the response as "totally unacceptable".

Iran's Foreign Minister Abbas Araghchi said he had received "elements" of a U.S. proposal for a potential nuclear deal following five rounds of talks mediated by Oman.
