An Israeli military aircraft fired a missile at gunmen in the Gaza Strip on Friday, wounding two of them, Palestinian medical workers said.
An Israeli military spokesman confirmed there had been an air strike on Friday.
Medics in Gaza said they evacuated two fighters to hospital after an Israeli air strike in northern Gaza, reported World Bulletin.
After Israeli missiles, Hamas said it fired 8 rockets at the city of Sderot. Two hit the town causing damage to buildings, Israeli police spokesman Micky Rosenfeld said. One Israeli was treated for shrapnel wounds.
Meanwhile, Israel has still shut border crossings with the coastal territory, blocking food and fuel supplies.
United Nations aid agencies supplying Gaza said they were out of food to distribute to 750,000 Palestinians.
"People are going to start getting hungry," said U.N. spokesman Christopher Gunness.
On Friday, some Gaza bakeries posted notices limiting the purchase of bread.
The U.N. on Thursday said its warehoused food supplies were finished and unless a re-supply convoy of trucks was allowed through Palestinians relying on food aid would also run out.
