Gaza City: Three Palestinians were killed by Israeli soldiers in the northern Gaza Strip, the Palestinian health ministry said Sunday, hours after three rockets were fired at Israel from the blockaded enclave.The ministry said another Palestinian was hospitalised in the shooting that came after the Israeli army said an attack helicopter and tank had fired at “armed suspects” along the barrier that separates Israel from Gaza.”We just identified a number of armed suspects from Gaza approaching the security fence with Israel. We fired towards them,” the army said a statement posted on its Twitter account.
