Beijing - An earthquake measuring 6.0 on the Richter scale hit Qingchuan county in south-western China's Sichuan province and nearby areas on Thursday afternoon, injuring at least five people.

The State Seismological Bureau said the quake at 3:09 pm (0709 GMT) mainly affected Qingchuan and the neighbouring county of Ningqiang in Shaanxi province.

At least five people were reported injured in the two counties after the quake, the official Xinhua news agency said without giving further details.

Qingchuan and Ningqiang were hit by the 8.0-magnitude quake in Sichuan on May 12, which killed at least 70,000 people and left nearly 20,000 missing.

The doctors have expressed concerns over growing air pollution in the city of Beijing. Beijing is going to host Olympic game in this year. The polluted air will be dangerous both for sportsmen and spectators of game. Air pollutants with fine size make the blood sticky and thicker. Pollution causes irritation of lungs and secretion of substance, interleukin-6, which can cause blood clotting. If clots enter into the lungs and cause pulmonary embolism, a person may die.

Beijing - China and Russia signed a final agreement on disputed border areas on Monday, with Russia reportedly conceding 174 square kilometres, including two small islands in a border river.

"We just signed a protocol on the eastern part of the Sina-Russian border," Yang told reporters at a joint press conference.

"It means that 4,300 kilometres of border between us has been demarcated," he said.
