Pakistan, Oct. 20 -- Israel launched a series of strikes in Gaza on Sunday in response to attacks on its forces, the military said, shaking an already fragile ceasefire in the shattered enclave as it traded blame with Hamas for violating the truce.

Residents in Gaza and local health authorities said that Israeli airstrikes and tank fire across the enclave killed at least 11 people.

An Israeli military official said that further strikes against Hamas targets may still be launched, in retaliation for at least three attacks on Israeli troops on Sunday.

The Israeli military said that airstrikes and artillery fire targeted fighters in the southern area of Rafah who had launched an anti-tank missile and fired on its soldiers.
