The United States' top law enforcement official says the recent terrorist bombings in Britain and Egypt could be the work of al-Qaida.

Attorney General Alberto Gonzales cautioned that officials are still investigating the bombings, which together killed some 140 people. But in an interview with CNN television, Mr. Gonzales said the July 7 attack on London's transit system and the July 23 bombing at Egypt's Sharm-el-Sheik resort both have the appearance of al-Qaida involvement.

Groups that say they are affiliated with al-Qaida have claimed responsibility for the attacks.

Sunday's Washington Post cites intelligence officials and terrorism experts as saying that Osama bin Laden or his aides may have sponsored the two operations from afar.

The officials say the attacks fit into al-Qaida's pattern of conducting multiple bombings against civilian targets that are designed to scare Westerners and shake the economy.
