Attack on police station in China's Xinjiang province 18 July 2011 Last updated at 10:29 GMT

Several people have been killed in China's restive Xinjiang province in an attack on a police station.

Two security personnel and several of the attackers died in the incident in the city of Hotan, state media reported.
The situation is now said to be "under control".
Xinjiang is the home to a largely ethnic Uighur population which feels increasingly pressured by Han Chinese migration and strict controls.
In 2009, deadly ethnic riots erupted in Xinjiang after tensions flared between the Muslim Uighur minority and the Han Chinese.
There have also been a number of blasts in Xinjiang in the past, which the government blames on Uighur separatists.
But Uighur activists and human rights groups accuse Beijing of using the issue to crack down on Uighur dissidents, who have complained that waves of Han Chinese migrants have marginalised the Uighur culture.
