American Killed in Afghan Attack

Another deadly day in Afghanistan: at least 19 civilians were killed in a roadside bomb attack, one day after at least 63 Shiites were killed in multiple bombings. President Hamid Karzai cut short his visit to Europe to return to Afghanistan after yesterday's assault, which targeted worshipers on the holiest day on the Shiite calendar. A Pakistani-based Sunni group claimed responsibility for yesterday's attack, which raises fears that a new strain of sectarian violence could be added to the unstable country. The U.S. Embassy confirmed that an American citizen was killed in yesterday's attacks.
