Kabul, Afghanistan: The Taliban infiltrated an Afghan intelligence base on Monday killing dozens who worked for the agency in what officials said was one of the single deadliest attacks against the intelligence service in the 17-year war with the Taliban.

Taliban insurgents immediately claimed responsibility for the attack, which some security officials in Kabul said had killed more than 120 people inside the facility and wounded many others. But provincial officials insisted that the toll was much lower. Spokesmen for the intelligence agency could not be reached on Monday night to comment.

A Humvee rammed a training compound of the national intelligence agency in Wardak Province.

The attack followed an equally brazen Taliban assault on Sunday on a government convoy in Logar province, in which the provincial governor barely escaped and eight of his bodyguards were killed when a suicide bomber in a vehicle rammed their convoy.
