Insurgents gained entry into the base using a car bomb before opening fire. Some reports estimate the dead at over 100. It is one of the deadliest attacks on the secret service to date and follows a string of setbacks for the army. Monday's attack on the National Directorate for Security (NDS) base in central Wardak province came hours before the Taliban held another round of peace talks with US diplomats in Qatar. Reports say the base in Maidan Shahr, about 30km south-west of Kabul, is a training centre for pro-government militia members. A second car bombing attempt was foiled by Afghan security forces and three would-be suicide attackers were killed, according to the NDS.
