The Hamas military warned of further rocket attacks on Israel's strategic interests, including Ben Gurion airport east of Tel Aviv, a spokesperson said on Wednesday, adding that an Israeli airstrike in Gaza had failed to kill its commander, Mohammed Deif.

Abu Obeida, the spokesman for Hamas' military wing, cautioned international airlines against flying into Israel starting Thursday, suggesting hostilities may continue. Earlier in the conflict, airlines suspended their flights into Israel after a rocket landed in a town near Israel's main international airport.

Israel has not formally commented on the strike but local media quoted an anonymous official as saying it was meant to hit Deif.



Sami Abu Zuhri, a Hamas spokesman, told the group's TV station Al-Aqsa that Deif "wasn't even in the location when they bombed it."



Twenty-one people were wounded in a separate airstrike that hit the building that houses Al-Aqsa TV, said al-Kidra, of the Hamas-run Gaza Health Ministry.

Air raid sirens wailed in southern Israeli cities Wednesday morning warning of incoming rockets from Gaza. There were no reports of injuries, though a piece of a rocket that was intercepted near Tel Aviv fell on a busy road on Tuesday night.
