SRINAGAR (Agencies) - Tens of thousands of Kashmiris massed in Srinagar on Friday to protest against India's rule, in the second major demonstration here this week. Protesters began marching from early morning towards the site of the rally, the "Martyrs' Cemetery" where many of those killed in the nearly two-decade-old revolt against New Delhi's rule are buried. "The rally is to show to the world that we are against India's occupation of Kashmir," said All Parties Hurriyat Conference leader Shabbir Shah, who has spent more than 20 years in Indian jails. The demonstrators, carrying black and green flags symbolising Islam and mourning, shouted "azadi" or freedom. It was the second show of strength by Kashmiris this week in Kashmir. On Monday, tens of thousands of Muslims took to the streets of Srinagar to demand that the United Nations recognise the Himalayan region's right to self-determination. India says decades-old UN resolutions are "obsolete." Security was tight for Friday's rally, which closed down shops, businesses and schools in Srinagar. "Security forces have been deployed in strength across Srinagar to maintain law and order," said Indian police officer Pervez Ahmed. "We have sufficient reserve forces to deal with any eventuality," he said. People from other towns and villages arrived in cars, jeeps, buses and trucks with those on board chanting, "We want freedom." Last week 22 protesters were shot dead by security forces in the occupied valley during Muslim protests against the blocking of the region's main highway by Hindu hardliners.
