Two teenagers were killed Wednesday by a blast in the North Caucasus republic of Dagestan after they picked up a package loaded with explosives, local police said, RIA Novosti reports.
Two more people were hospitalized with injuries from the blast, a police spokesman said. He denied earlier reports that a third victim died of injuries in the hospital.
The bomb, equivalent to two kilograms of TNT, was left by the roadside near a market in the center of republican capital Makhachkala, police said.
Unidentified attackers pelted a police car with bullets hours earlier in the city of Buinaksk, 48 kilometers southwest of Makhachkala, killing three and injuring two. Police did not say whether it considered the attacks to be linked.
