CAIRO, Egypt (AP) _ Two trains collided Saturday in northern Egypt, injuring at least 50 people and killing an undetermined number, police said.

Police said the trains hit each other head-on near the station at Shirbin, 80 miles northeast of Cairo. The town is on the main line between Cairo and Damietta at the northeastern edge of the Nile Delta.

The Interior Ministry confirmed the accident, and said officials still were trying to determine casualties.

Police said there were about 50 casualties, but said they could not immediately determine how many of those were deaths.

Egypt has a history of train accidents with high death tolls. In November, 47 people were killed when a train jumped its tracks near Kafr el-Dawar, a Delta town 20 miles southeast of the port of Alexandria.
