A tunnel under the border between the Gaza Strip and Egypt collapsed on Saturday, but Palestinian security officials weren't immediately able to say whether it served to smuggle contraband or weapons to Palestinian terrorists.
A Palestinian security official said one man was dug out from the rubble and an undetermined number of others were trapped in the debris.
The official, Col. Hussein Abu Omar, said the tunnel was dug from inside a Gaza house some 100 meters from the border with Egypt. It was not clear how far it extended into Egypt.
Abu Omar had no details about the owner of the house or further information about the tunnel.
The man who was pulled out of the debris was taken to a hospital, then left without being questioned by police, hospital and security officials said.
