Israeli aircraft carried out a series of airstrikes at militant sites in the Gaza Strip early Wednesday, the first such raids since a shaky cease-fire ended the war with Hamas last month.

The airstrikes targeted facilities used by Hamas militants for meetings to plan attacks, the Israeli military said, blaming the group for any act of violence emanating from Gaza. There were no immediate reports of casualties.

Israeli airstrikes killed at least six people across the Gaza Strip and destroyed the home of a large extended family early on Wednesday. The military said it widened its strikes on militant targets to the south amid continuing rocket fire from the Hamas-ruled territory.

Residents surveyed the piles of bricks, concrete and other debris that had once been the home of 40 members of al-Astal family. They said a warning missile struck the building in the southern town of Khan Younis five minutes before the airstrike, allowing everyone to escape.

Israeli warplanes struck the Gaza Strip early Saturday after repeated salvos of rocket fire into Israel followed a second night of clashes between Palestinians and police in Israeli-annexed east Jerusalem.
