Separatists have issued a call for a three-day shutdown till February 11, which date marks the death anniversary of JKLF founder Mohd Maqbool Bhat. Bhat was hanged and buried inside Tihar Jail 20 years ago.
Soon after daybreak, police vehicles fitted with public address systems made announcements across the Valley about the imposition of restrictions in vulnerable areas, sources added.
Authorities have detained several top separatist leaders ahead of Guru's death anniversary.
Hardline Hurriyat Conference leader Syed Ali Shah Geelani, who returned home to the Valley yesterday from Delhi, was put under house arrest soon after his arrival here.
JKLF chairman Mohd Yasin Malik, who had announced that he would hold a protest at the historic Lal Chowk today, has gone underground to avoid being taken into preventive custody.
All roads leading to Lal Chowk have been sealed and the public is not being allowed to proceed towards the area.
