Gaza: Israeli forces killed at least nine  Hamas fighters in the Gaza Strip on Tuesday, a day after a suicide bombing in Israel claimed by the group. 

Seven of the Hamas men were killed by an air strike on a security post in southern Gaza and two other armed members of the movement were shot dead by Israeli soldiers near the border with Egypt.

Israeli sonic booms shook windows in Gaza City, fraying nerves and raising fears of an intensive Israeli military campaign in retaliation for Monday's bombing in the desert town of Dimona.

A Hamas security officer said its members were ordered to take "all necessary precautions", including turning off cellular phones that could be tracked by Israeli drones that routinely fly over the Gaza Strip.

Meanwhile, Hamas leaders in Nablus called on their members to surrender their weapons and urged comrades in Gaza to give up control of the territory.

At a press conference in the northern West Bank town, local Hamas leader Mousa Al Kharraz hailed the improved security situation in Nablus.
