KABUL, Oct. 27, 2009 (Reuters) Intense machinegun fire and an explosion resounded in central Kabul on Wednesday morning, but the cause of the firefight was unclear.
Sporadic gunfire was heard and plumes of black smoke rose above buildings in the Afghan capital.
A Reuters witness said a number of streets had been cordoned off by the police as the gunfire continued. Sirens reverberated in the capital.
An increasingly resurgent Taliban have vowed to stage attacks ahead of a second-round run-off in Afghanistan's presidential election on November 7.
