The Israeli military says it struck several Hamas militant sites in Gaza in response to incendiary balloons with explosives launched from the strip.

The military says it hit the sites in northern Gaza Strip early on Thursday. It says that afterward, two rockets were fired out of Gaza. There were no injuries on either side.

The brief flareup marked the first Israeli strike in more than a month. Egyptian mediators have been trying to reach a long-term cease-fire during the lull.

Israel previously scaled back the permitted fishing zone off Gaza's Mediterranean coast following a rocket attack.

Israel says it holds Gaza's Hamas rulers responsible for all attacks from the coastal territory. The sides have engaged in several rounds of cross-border fighting over the past year.
