Bomb blast hits official's car in Russia's Dagestan region

A bomb blast ripped through a car in Russia's violence-plagued Dagestan region Wednesday, injuring a top railway official and his driver, law enforcement authorities said, adding that the two were hospitalized. Attacks on officials and law enforcement authorities are common in Dagestan. The province in Russia's restive North Caucasus is troubled by violence linked to the separatist conflict in neighboring Chechnya, a police crackdown on Islamic militancy and internal criminal disputes and power struggles.
