The United Nations has called on Israel to allow aid into Gaza after suspending humanitarian deliveries, as talks on a truce extension hit an impasse. Both Israel and Palestinian sources reported Israeli military strikes in the Gaza Strip, resulting in the deaths of at least four people. The first phase of the ceasefire has ended, with Israel announcing a truce extension until mid-April, which Hamas has rejected. The UN has called for humanitarian aid to flow back into Gaza immediately, and the head of the UN humanitarian agency has stated that Israel's decision to halt aid may be in violation of international law.
