Israeli aircraft hit two training camps in the Gaza Strip overnight in response to a rocket fired toward the south of the Jewish state, sources on both sides said Wednesday.

There were no reports of casualties from either the rocket or the retaliatory strikes.

The raids hit military training camps in the northern and central Gaza Strip operated by the territory's Islamist rulers Hamas.

Salafists claiming links with Islamic State jihadists have taken responsibility for recent rocket fire, but Israel holds Hamas responsible for all such incidents and nearly always responds with air strikes.

Palestinian in Gaza have fought three wars with Israel since 2008.
