Report: Insurgents strike Afghan intelligence headquarters

A car bomb was detonated outside the headquarters of Afghanistan's National Directorate of Security in Helmand province, according to the Associated Press. 

The headquarters, stationed in Lashkar Gah, was the directorate's main operational hub for intelligence operations in and around Southern Afghanistan, recent reports state. 

The two Afghan soldiers killed in the attack were standing guard at the headquarters when the bomb went off. The majority of the Afghan civilians were wounded when the car bomb hit the adjoining apartment building to the Lashkar Gah facility. 

Neither Taliban leaders nor any other Afghan terror group has claimed responsibility for the attack.

The bombing comes as Afghan intelligence have stepped up their efforts to root out Taliban infiltrators from the Afghan National Security Forces (ANSF). 

Taliban double agents operating inside the ANSF have been largely responsible for the recent spate of "insider" attacks by Afghan troops against U.S. and NATO forces. 

Afghanistan's military and intelligence leaders have begun planting dozens of intelligence officers within the military and national police forces across the country to ferret out Taliban operatives or sympathizers.

Afghan intelligence officials have even gone so far as to place a ban on all cellphones by new ANSF recruits as a way to limit potential communication between those recruits and Taliban commanders.

American counterintelligence operatives have already been embedded within U.S. military units and Afghan security forces at the battalion level and above, according to the Pentagon.

But the attacks continue with U.S. and coalition forces no closer to rooting out the terror group's presence within the Afghan forces. 

"As for what percentage of the insider threat is related to infiltration or radicalization, I mean, it's really difficult to determine," Chairman of the Joint Chiefs of Staff Gen. Martin Dempsey said in September. 

"I'm sure a certain percentage of it is. And we're treating it … as a threat," he told reporters at the Pentagon at the time.
