Security Tightened

NAZRAN, Ingushetia — Federal troops on Friday tightened security at checkpoints across Chechnya and posted extra guards near administrative buildings following a deadly bomb blast in Grozny, officials said.

At least 10 people were killed and 16 were injured on Thursday when a powerful bomb went off inside a car parked near a police station in Grozny.

An official in the pro-Russian Chechen administration said police had detained three men in Grozny in connection with the bombing. Twelve others were detained in a sweep of the neighborhood where the bombing occurred.
