Qa'dah 14, 1431 / Oct. 22, 2010, SPA -- A roadside bomb killed a district governor and two of his aides in Afghanistan's eastern Nangarhar province on Friday in the latest attack targeting a local government official, the Afghan Interior Ministry said. According Reuters, Violence is at its worst level since the Taliban were toppled in 2001 by U.S.-led troops and later began their campaign to bring down the government of President Hamid Karzai and drive out thousands of foreign troops deployed in Afghanistan. The bomb exploded as a car carrying the head of Dor Baba district and four others passed through a remote area bordering neighboring Pakistan's restive tribal belt, the Interior Ministry said in a statement. Two policemen were wounded in the attack, it said.
