Human Rights Day has been observed every year on Dec. 10 since 1948, when nations in the UN General Assembly adopted the Universal Declaration of Human Rights.
"On Human Rights day we must appeal to the world's conscience, to upholders of international law & to the UNSC [UN Security Council] to act against the illegal annexation of IOJK [Indian-occupied Jammu and Kashmir] by the Indian Occupation govt.," Khan said on twitter.
Condemning the Indian government's "siege" of Kashmir, he demanded "an end to the gross abuse & atrocities being inflicted on Kashmiri men, women & children by Indian Occupation forces in violation of all Int Humanitarian & Human Rights Laws."
"We salute & stand resolutely with the brave Kashmiris struggling for their right of self determination," Khan added.
Meanwhile, the day is being observed as a "black day" by several groups in the Indian and Pakistani sides of Kashmir, against New Delhi's controversial move.
