They later submitted a memorandum at the Pakistan High Commission.
The protest was led by the All India Kashmiri Samaj (AIKS), which is a central body for several Kashmiri Pandit organisations in India and abroad.
"The protest was organised against Pakistan's gross interference in the internal affairs of our country, as also Pakistan's open support to known terrorists and their sympathizers in Kashmir," AIKS said in a statement.
The demonstration was earlier planned outside the Pakistan High Commission in Chanakyapuri here but police barricaded a certain stretch of Shanti Path, citing security concerns, therefore the protesters later assembled at Teen Murti Marg.
