Former Philippine President Rodrigo Duterte said he takes full responsibility for his administration's "war on drugs", in a video message posted on his Facebook account, as he braces for a legal battle at the International Criminal Court.

At least nine Palestinians were killed, including two local journalists, and others wounded on Saturday in an Israeli airstrike on Gaza’s northern Beit Lahiya town, Gaza’s health ministry said, as Hamas’ leaders hold Gaza ceasefire talks with mediators in Cairo.

Following the reported strikes, the deadliest since the ceasefire took hold on January 19, Hamas accused Israel of a "blatant violation" of the truce which largely halted more than 15 months of fighting.
