Israeli aircraft shelled two locations in the southern Gaza Strip and one in the north Thursday morning, damaging the already destroyed Yasser Arafat International Airport, a residential area, and an empty field.

Eyewitnesses said at least two F16 warplanes were involved in the operation, and one Gaza City resident said a strike targeted the Abu Jerad area, damaging several homes.

No injuries were reported in any of the locations, described by an Israeli military statement as a weapons manufacturing facility south of Gaza City, a "terror tunnel" near Rafah, and unspecified terror activity at the defunct airport.

The army said a "terror tunnel was dug approximately one kilometer away from the security fence and is intended for infiltrating into Israel and executing terror attacks against IDF soldiers and Israeli civilians."

The military said the bombings were in retaliation for a "rocket that was fired at Israel and damaged a factory in the Sdot Negev Regional Council" the day before.

No armed group in Gaza claimed to have launched the homemade projectile, but the Abu Ali Mustafa Brigades - the armed wing of the Popular Front for the Liberation of Palestine - said they fired an RPG at an Israeli bulldozer destroying agricultural lands in areas south of Gaza City.

An Israeli military spokeswoman said she was unaware of that incident.
