A pair of brutal explosions interrupted celebrations marking the end of Ramadan in the Chechnyan capital of Grozy on Tuesday evening. CNN reports:

Two blasts -- the second coming after police and passersby had gathered at the site of the first -- killed seven people and wounded 18 Tuesday evening in the Russian republic of Chechnya, according to the Russian news agency RIA Novosti.

The state-run agency said the first blast occurred when officers attempted to detain a suspected militant in the Chechen capital of Grozny. About 30 minutes after that explosion, a second blast hit the same area after people had gathered there, RIA Novosti said.

So far, no one has taken credit for the attack.
