Two explosions went off outside an Interior Ministry base Thursday in a Russian republic bordering Chechnya, wounding eight people, the ministry reported.
Russian news reports said the first explosion was a bomb; the cause of the second blast was not immediately clear.
The first explosion occurred at the gates of the base just south of Makhachkala, the capital of Dagestan, the regional Interior Ministry said. The timing of the second blast wasn't clear: it happened between 10 minutes and an hour after the first.
A bus with base personnel had just arrived when the first explosion went off.
