Hardline separatist leader Syed Ali Geelani on Monday demanded the release of political activists in prisons in the Kashmir Valley before Eid-ul-Fitr.

The octogenarian said in a statement that Eid would fall on June 25 or 26, marking the end of the holy month of Ramadan.

Geelani said the detention of political activists under the harsh Public Safety Act (PSA) in Jammu and Kashmir was nothing short of "extremism".

He said separatist leaders like Asiya Andrabi, Masarat Alam and others were in different jails.

Calling the 2016 summer unrest in the Valley as "people's uprising", Geelani alleged that over 20,000 people and activists were arrested last year and more than 500 of them were still under detention.

He also sought the intervention of Amnesty International and the International Committee of the Red Cross (ICRC) on the issue.
