The Israeli military said Sunday that it struck a Hamas outpost in the Gaza Strip after an explosive device was hurled over the border fence in northern Gaza.

No injuries were reported as a result of the strike, which took place east of Beit Hanoun.

The chain of events marks the fourth such flare-up since last week, when Israel attacked a Hamas outpost in response to the first airborne firebomb launched from Gaza since November.

Last Wednesday, the Israeli air force struck several targets in Gaza after an airborne incendiary device damaged a home in the Eshkol region of southern Israel.

The military said attack helicopters and fighter jets struck a military compound used by Hamas in the central Gaza Strip.

On Saturday, Israeli aircraft struck a Hamas target after balloons carrying explosive devices drifted over the border fence into Israel.

A senior Hamas political official told Haaretz in February that the organization did not want to go “all out” against Israel, so as to allow Egyptian-mediated talks to continue.

However, Hamas said that Israel has been trying to impose quiet on the Strip by means of Qatari money, and senior Hamas officials said recently that the organization would not stop the protests at the border fence in exchange for the money.
