JERUSALEM - Prime Minister Benjamin Netanyahu ordered the Israeli military to retaliate after rocket attacks by Gaza Palestinian militants followed the end of a three-day truce on Friday, an official said.
"The Israeli prime minister and defence minister have ordered the IDF (Israel defence forces) to retaliate forcefully to the Hamas breach of the ceasefire," an official said in a statement.
The army confirmed it had "targeted terror sites across the Gaza Strip," with a spokeswoman telling AFP that no Israeli soldiers had entered the Palestinian territory.
The Palestinian interior ministry and witnesses said Israeli warplanes struck Jabaliya in northern Gaza, as well as Gaza City and the centre of the Palestinian enclave.
No casualties were immediately reported.
Witnesses also reported artillery shelling east and north of Gaza City.
