NATO helicopters fired rockets at gunmen on the rooftop of a besieged Kabul hotel early on Wednesday, ending a more than four-hour standoff between militants and police that left at least seven dead and eight others wounded, Afghan officials said.

Interior Ministry spokesman Sediq Sediqqi said six suicide bombers attacked the Inter-Continental hotel frequented by Afghan officials and foreign visitors. He said two were killed by hotel guards at the beginning of the attack and four others either blew themselves up or were killed in the airstrike or by Afghan security forces.
