Asadullah Khalid was under treatment in US after he was injured in a suicide attack in capital Kabul in December 2012.
Khalid wrote in his twitter account on Friday that he was back to Kabul. In a separate twitter message earlier in February, Khalid had said that his health is much better now.
A suicide bomber posing as a Taliban peace emissary seriously injured Asadullalh Khalid in December last year. He targeted inside one of the Afghan intelligence agency’s guesthouses in Kabul’s central Taimani neighborhood.
The bomber had secured face-to-face meeting in Kabul with Asadullah Khalid for several months, by posing as a Taliban messenger potentially interested in helping broker peace talks.
He was actively supporting the anti-Taliban uprisings in insurgent-held areas of eastern Afghanistan, and often accused the Pakistani intelligence services of fomenting the insurgency.
Khalid was minister of border, tribal and ethnic affairs before he was elected as the Afghan intelligence chief. He also served as Ghazni and Kandahar provincial governor from 2001 to 2005.
Afghan officials had said that the attack on Asadullah Khalid was plotted in Quetta city of Pakistan and the suicide bomber had came to Kabul from Pakistan.
