Israeli aircraft attacked Hamas targets overnight Wednesday after a day of violent protests against Israeli troops.
The Palestinian provocations included the launching of a rocket toward Israeli communities and the flying of incendiary devices across the border using balloons.
Israeli tanks also took part in the response, with Palestinians reporting shelling of a Hamas outpost in the southern Gaza Strip.
Gaza's Health Ministry says a 15-year-old Palestinian has died from Israeli gunfire on Wednesday when protesters clashed with Israeli troops along Gaza-Israel border fence.
Saif Abu Zaied was wounded in the head Wednesday and died at a hospital, the ministry said early Thursday.
The protests on Wednesday saw dozens of youths engaged in violent protests involving firebombs and laser lights directed at Israeli forces along the border fence.
The night skirmishes are complementary to the weekly daytime protests that Gaza's Hamas rulers have staged for a year.
