Israeli airstrikes kill at least 33 in Gaza Strip in deadliest attack so far

Health officials say up to 50 injured, as militants launch more rockets at Israel than in the whole 2014 war

At least 33 Palestinians have been killed in airstrikes and 50 injured, health officials in the Gaza Strip have said, in the deadliest single attack since fighting broke out between Israel and the Palestinian militant group Hamas a week ago.

Air-raid sirens sounded for the seventh consecutive day across southern Israel as Hamas and other militant groups in Gaza launched more rocket attacks into the country - and reaching further - than in the entirety of the 2014 war.
