The abduction came as Egyptian demonstrators battled security forces for a second day in downtown Cairo to protest the deaths of more than 70 people killed Wednesday night in a fight between rival fans after a soccer game.
The abduction followed a string of violent crimes in Egypt recently, including the shooting of a French tourist during the armed robbery of a currency exchange shop in the Red Sea resort town of Sharm el-Sheikh last week.
A police captain in Sinai said authorities believe that the gunmen who kidnapped the American women Friday might have been members of a Bedouin tribe trying to secure the release of fellow tribesmen detained in last week’s shooting.
The captain, who spoke on the condition of anonymity, said the kidnappers probably would demand that the tribesmen be freed in return for the Americans’ release.
Last month in the Sinai Peninsula, a group of 25 Chinese workers was kidnapped by Bedouin tribesmen and then freed a day later. The tribesmen had kidnapped the workers to press their demand for the release of detainees held over bombings in the peninsula between 2004 and 2006.
Egyptians’ faith in the ability of the ruling military council to maintain order was further shaken by the post-soccer match melee in Port Said on Wednesday, which left more than 70 people dead.
Protests that have erupted since the violence have resulted in more bloodshed, with at least three people killed in clashes with police overnight Thursday and on Friday.
Riot police guarding the Interior Ministry in downtown Cairo on Friday beat back waves of protesters with tear gas and rubber-coated bullets, witnesses said. Protesters blamed the police forces under the ministry’s supervision for not preventing the fight at the stadium in Port Said.
“We are here to break into this dirty, corrupted building, and we will stay here until we make it,” said Mina Rizk, 23, a water company employee. “This government isn’t doing anything.”
