A group of youth, with faces covered and carrying a black banner resembling Islamic State flag, marched from Jamia Masjid towards Nowhatta chowk soon after the Friday prayers, official sources said.
They said Pakistani flags were also waved by some youth in the area before police swung into action and chased away the protestors. No arrests have been made so far.
Reports from Kupwara in north Kashmir said Pakistani flags were hoisted at some places there too after the Friday prayers, the sources said.
Hardline Hurriyat Conference headed by Syed Ali Shah Geelani had called for protests after Friday prayers against the killing of Tehreek-e-Hurriyat activist Altaf Sheikh by unidentified gunmen on Tuesday.
