According to them 15 people were killed and as many wounded in the attack that lasted over six hours.
Officials said a car bomb was detonated close to the entrance of the compound at about 11.30am and was followed by two gunmen storming the building.
A number of employees were able to escape during the course of the day, but many remained trapped inside.
Throughout the day gunfire could be heard coming from the area while plumes of black smoke could also be seen soon after the attack started.
This comes just three days after a complex attack on a midwife training center in Jalalabad.
