Israel launched air strikes on Gaza Friday in response to militant rocket fire from the Palestinian enclave, as tensions rose following the deadliest army raid on the occupied West Bank in years.

Israel said it had carried out at least two rounds of strikes targeting Hamas militants, following waves of rocket launches towards southern Israel. 

There were no reported injuries on either side and most of the Gaza rockets were intercepted by Israel's air defense system. 

No Palestinian group in Gaza has claimed responsibility for the rockets, but Hamas had vowed to respond to Thursday's Israeli raid in the West Bank, which killed nine people.
