Violent clashes between Kyrgyz and Uzbeks leave 49 dead and hundreds of wounded
The causes of the unrest are still unknown. Osh is the second largest city in the country. It is home to a large Uzbek community, which has backed former President Kurmanbek Bakiyev who was ousted on 15 April.
"The situation in the Osh region has spun out of control," interim President Roza Otunbayeva said. "Attempts to establish a dialogue have failed, and fighting and rampages are continuing. We need outside forces to quell confrontation."
Since yesterday, Kyrgyz troops have been patrolling the city, which is under a state of emergency. However, thousands of people fled towards the border with Uzbekistan.
The unrest is the worst violence since former President Bakiyev was toppled in a bloody uprising in April and fled the country.
