GAZA CITY, Gaza Strip – The Israeli army says it carried out airstrikes on a weapons workshop east of Gaza City and two weapons smuggling tunnels under the Gaza-Egypt border.
Palestinian health officials reported no injuries.
The army says Saturday's strikes were in response to a mortar shell and a rocket fired at Israel from Gaza the day before.
A small extremist group, Ansar al-Sunna, said on Friday it fired two rockets at Israel.
Exchanges of fire between Israel and Gaza militants have increased in recent months after a period of relative quiet following Israel's Gaza offensive, which ended Jan. 18.
The Israeli army said about 60 rockets and mortar rounds have been fired at Israel in the last three months. Airstrikes followed some of those attacks.
