In Ankara, a demonstrator suffered second-degree burns after setting himself on fire during a rally by several hundred ethnic Uighurs, officials said. He was identified as a 35-year-old from Turkey's local Uighur community, an ethnic minority in China seeking independence or greater autonomy.

In Katmandu, Nepal's capital, thousands of Tibetan exiles demonstrated at the Chinese Embassy, shouting, "China, thief: Leave our country. Stop killing in Tibet."

Police forcibly dispersed the protesters, some of whom tried to storm the embassy, police official Ramesh Thapa said. More than 1,000 people were detained for violating a ban on demonstrations — the largest number of Tibetans detained in a single day in Katmandu.

More than 2,000 protesters marched in Dharmsala, a north Indian hill town that is home to the Tibetan government-in-exile and the Dalai Lama, Tibet's spiritual leader.

There were the victims: 70 paramilitary police officers out for a morning jog, and whose daily routine had been secretly monitored for a month by the attackers.

There was the group: A shadowy organization advocating independence for Muslims in western China that government officials now say started a master plan in the spring to disrupt the Olympic Games through terrorism.

Those are the elements that Chinese officials in Kashgar put forward on Wednesday in trying to explain the deadliest attack on Chinese security forces in years. On Monday, the two men, both of them Uighurs - the Turkic Muslim group once dominant in the western region of Xinjiang - rammed into the joggers with the truck, tossed explosives and then stabbed the victims, leaving 16 dead and 16 wounded, Chinese officials said.

The men were arrested and have confessed to their crimes, and the trial of one has already begun, said Shi Dagang, party secretary of Kashgar.
