Yahoo Buying Tumblr for $1.1 Billion

The news of the Boston Marathon bombings circled the globe, and resonated here in Dagestan, a majority Muslim republic in Russia, on the shores of the Caspian Sea. Last year, Tamerlan Tsarnaev, the older of two brothers suspected of the bombings and a long-time Boston resident, returned to Dagestan, where he had lived for a year during his youth. Dagestan was the land of his maternal ancestors. But in the last two years, this republic of 3 million people has gained notoriety as the region with the highest level of political and religious violence in all of Russia.
