No casualties reported after strikes, which came just hours after rockets from the enclave hit southern Israel.
Fragments from a missile fired by an Israeli aircraft killed a 10-year-old Palestinian boy in the Gaza Strip, Palestinian medical officials said, hours after several rockets were launched into Israel.
A statement by the Israeli military said aircraft had targeted four training camps belonging to Hamas after four missiles landed in open areas in southern Israel late on Friday.
No casualties were reported from the rocket strikes.
Residents of Beit Lahiya in the northern Gaza Strip said Yassin Abu Khoussa died after missile debris hit his home, which is next to a training camp.
His six-year-old sister was wounded, the medical officials added.
The Gaza health ministry said Israel carried out five air raids on Hamas facilities.
The boy was the first fatality from an air strike in Gaza since October.
The Israeli army said that since the beginning of the year and including Friday’s salvo, seven rockets have been fired from the Gaza Strip into Israel.
Gaza rocket fire has tapered off significantly since a 2014 war when more than 2,100 Palestinians, mostly civilians, and six Israeli civilians and 67 soldiers were killed.
