Suicide attacks kill 12 in Russia

---

MOSCOW, Mar 31 (Internet): Two explosions killed at least 12 people in the volatile North Caucasus region Wednesday in what appeared to be attacks targeting the police, investigators from the Russian prosecutor's office said.
One of the explosions was caused by a suicide bomber wearing a police uniform, officials said.
The bombings, which also injured at least two dozen people, occurred in Dagestan, a region of southern Russia that borders Chechnya, where attacks against the police occur almost daily.
The attacks came two days after two female suicide bombers set off explosions in the Moscow subway during the morning rush hour, killing 39 people, and they seemed to offer a further challenge to the Russian authorities.
On Wednesday, Rashid G. Nurgaliyev, Russia's interior minister, ordered the police to increase security in public places like theaters, schools and universities.
