The UN has sanctioned ISIS' South Asia Branch, a group formed in 2015 by a Pakistani national and a former commander of the TTP, for its links with al-Qaeda and involvement in several deadly attacks in Afghanistan and Pakistan that killed over 150 people.
The United Nations Security Council's 1267 Al Qaeda Sanctions Committee on Tuesday sanctioned Islamic State in Iraq and the Levant - Khorasan (ISIL-K), which is also known as 'ISIS' South Asia Branch, ISIL Khorasan, Islamic State's Khorasan Province' and 'South Asian Chapter of ISIL'.
The group is now subject to assets freeze, travel ban and arms embargo.
The Sanctions Committee said in a statement that ISIS-K was formed on January 10, 2015 by a former Tehrik-e-Taliban Pakistan (TTP) commander and was established by former Taliban faction commanders "who swore an oath of allegiance" to ISIS and its leader Abu Bakr al-Baghdadi.
ISISK has claimed responsibility for numerous attacks in both Afghanistan and Pakistan.
The Sanctions Committee said the group was listed as being associated with ISIS or al-Qaida for "participating in the financing, planning, facilitating, preparing or perpetrating" acts or activities by supplying, selling or transferring arms and related materiel.
It said the group engaged in "other acts or activities indicating association with al-Qaeda, ISIS, or any cell, affiliate, splinter group of al-Qaeda in Iraq".
The group had announced its formation in an online video in January 2015.
ISIS spokesman Abou Mohamed al Adnani had announced its expansion into the area historically known as Khorasan, by acknowledging ISISK leader's pledge of allegiance to al-Baghdadi and claiming the leader of the Islamic State had accepted his pledge and appointed him as governor of the Khorasan Province.
The Sanctions Committee said ISIS-K had carried out numerous attacks since its formation that have killed more than 150 people.
