The jets hit two sites, one in the southern town of Khan Yunis and another near Nusseirat in the centre of the Hamas-ruled strip, security officials said.
The Israeli military had no immediate comment.
The air raids took place after tensions rose along the Gaza border this week following clashes and a rocket attack on the Israeli city of Beersheva that hit a house, but caused no casualties.
It was the first rocket to strike Beersheva since the devastating 2008-2009 Gaza war, prompting Israeli Prime Minister Benjamin Netanyahu to warn Gaza militants not to "test" Israel.
