Israeli warplanes struck numerous Hamas posts in southern Gaza late Wednesday night after a small bomb attached to a bundle of balloons was launched into Israel from the Hamas-controlled coastal enclave.
The explosive device damaged the front window of a home in the Eshkol region.
No casualties were reported.
The bomb exploded near the home of Rachel Danzig, whose home was almost hit by a rocket fired from Gaza during the previous spat of hostilities.
"I'm shaking right now," she said. "The balloon exploded next to my house, I thought it was literally inside the house. It's scary because there's no deterrence. My neighbor has a hole in her garden, glass is shattered all over my home and everything moved from the blast. I'm still traumatized by the first time. My neighbor is absolutely frightened. She's 70 years old and is in shock.
"Over the past three weeks, they [Palestinians in Gaza] have launched a lot of balloons and because they do it at night, it's hard to stop it. People could get hurt," Danzig said.
"The Hamas terrorist organization bears responsibility for anything that occurs in the Gaza Strip and for all the consequences of its terrorist activity there," the IDF said in a statement.
