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.

The Israeli military said it struck militant targets around the towns of Khan Younis and Rafah, with 52 aircraft hitting 40 underground targets over a period of 25 minutes. Gaza's Health Ministry said a woman was killed and eight people were wounded in those strikes.

Hamas-run Al-Aqsa radio said one of its reporters was killed in an airstrike in Gaza City. Doctors at the Shifa hospital said his was among five bodies brought in early Wednesday. The fatalities included two people killed when warning missiles crashed into their apartment.

The latest strikes came as diplomatic efforts aimed at a cease-fire gathered strength and Gaza's infrastructure, already weakened by a 14-year Israeli blockade, rapidly deteriorated.
