At least nine people have been killed and several others injured in an Israeli strike in Beit Lahia, northern Gaza, the enclave’s Government Media Office said Saturday, making it the deadliest incident since a ceasefire went into effect in January.

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.

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.

Two back-to-back Israeli airstrikes in northern Gaza killed at least nine people on Saturday, according to Gaza civil defense. Witnesses say several of those killed were aid workers and journalists.
