Russian Interior Minister Rashid Nurgaliyev ordered increased security at important buildings and public places in Russia's North Caucasus republic of Dagestan after two explosions on Wednesday.
Nurgaliyev added that Russia's response to the terrorist acts in Moscow on Monday morning, when two suicide bombers killed 39 people on the city's subway, would be "tough and principled."
