URUMQI, China, July 11 (Reuters) - China raised the death toll from ethnic rioting in Xinjiang, giving for the first time the ethnicity of the dead, and a big security presence in the city at the centre of the strife prevented protests on Saturday.

The official Xinhua news agency said 184 people had died in the July 5 riots in Urumqi, the Xinjiang regional capital, and 137 of those killed were Han Chinese, who form the majority of China's 1.3 billion population. The previous death toll was 156.
