NALCHIK, Russia -- When Zarema Valgasova last saw her son, he was semiconscious and bleeding profusely from a badly broken arm with cigarette burns on his body - the result, she says, of police torture after his arrest.
After Thursday's attack by dozens of Islamic militants on police and security facilities in the southern Russian city of Nalchik, police rounded up more than three dozen people - most of them Muslim men.
The latest violence was in Kabardino-Balkiriya republic, a tense area ridden with poverty and corruption. It underscored the volatility of the Caucasus region where a long-running conflict in Chechnya is spilling over with increasing frequency to nearby republics.
At least 108 people, including 72 attackers, were killed in this week's fighting, according to a tally of accounts by officials, news reports and an Associated Press reporter.
Twenty-four law enforcement officers were killed and 51 were wounded, government officials said.
