Hezbollah has vowed to continue resisting Israel and is monitoring the Israeli army’s withdrawal from south Lebanon “with [our] hands on the trigger”, the militia said in its first comments since a ceasefire came into effect on Wednesday.

At least 21 people were killed in airstrikes in the past 24 hours, hospital officials said, and Israeli ground forces are pushing deeper into the north and south of the enclave.
