4 policemen killed in Ingushetia blast

A car bomb exploded near a police vehicle in the troubled North Caucasus region, killing four police officers, witnesses and officials said. The blast occurred in the center of Nazran, the main city of violence-plagued Ingushetia, which borders Chechnya.

Authorities said three to five other people, apparently civilians, were injured. The blast occurred after police responded to a call about a suspicious car.

Also, gunmen burst into a home in Ingushetia and killed three members of a Russian-speaking teacher’s family. It was the second such attack this summer, and it deepened fears that Russians were being targeted.
