The Umar Media TTP page, which has nearly 290 likes, has a message posted on November 22 seeking writers for "Ahyah-e-Khilafat", which is described as the "official quarterly magazine" of the Tehrik-e-Taliban Pakistan. 

"Dear brothers and sisters, 'Pen is mightier than the sword (sic)'. Now you have a chance to use this mighty weapon," the message says. 

Prospective contributors can write on "on topic of your choice, or on jihadi current affairs, history, Islamic movements, plight of ummah, etc etc", the message adds. 

An earlier message posted in October states that "Umar Media is proud to announce online jobs opportunities (sic)". 

The job "description (sic) is video editing, translations, sharing, uploading, downloading and collection of required data". 

The earlier message includes an email ID for contacting the Taliban and asks people to spread news about the Facebook page as the account may be deleted. 

US-based private intelligence organization SITE too said the Pakistani Taliban use Facebook as "a recruitment centre". 

In a statement, SITE said: "Through its official media arm, Umar Media, the TTP has taken to Facebook to recruit contributors for their media work and the group's forthcoming publication 'Ayah-E-Khilafat' (Sign of the Caliphate)." 

The TTP, currently led by Hakimullah Mehsud, has been behind scores of bombings and suicide attacks, a majority of them against the security forces, that have killed thousands in the past five years. 

In October, the TTP claimed responsibility for an attempt to assassinate teenage rights activist Malala Yousufzai, who is being treated in a British hospital after being shot in the head.
