A land mine in the Sinai Peninsula in Egypt exploded on Wednesday, killing three teenagers and wounding two others, a medical official said. Ibrahim Ali, head of the Emergency Unit in South Sinai, said that the five were working in a farm near the Suez Canal when the land mine detonated. He said that the bodies of the three teenagers were badly maimed by the explosion while the others were seriously wounded. They were transferred to a hospital in the port city of Suez. Egypt estimates that millions of land mines were planted on its northern coast and on the Sinai Peninsula during War World II and its wars with Israel.
