Kyrgyzstan’s violent spring is bleeding into summer. A fresh set of riots centered in Osh, the country’s second largest city, killed 12 people and injured 120 more on Thursday. The violence now threatens to rock a nation that is still on uncertain footing two months after its president was deposed in an ugly coup. The government responded by declaring a state of emergency and imposing a curfew on the city from 8 p.m. to 6 a.m. Gunfire was heard late last night and continued into the early hours of the morning, leaving several buildings on fire. No one is quite sure what prompted the riots, but the local media is reporting that it began with a large brawl in the city center—the region around Osh has a history of ethnic violence involving the large Uzbek minority.
