Olympics: Russia to boost Sochi security from June 1

Russia will boost security at 2014 Winter Olympics host Sochi from June 2013, the interior ministry said Tuesday, after the deadly attack on the Boston marathon raised alarm about sports security worldwide.

"From June 1, 2013, strengthened security measures will be put in place on the territory of the city of Sochi," it said in a statement, while insisting that security for visitors to Sochi had always been a "priority" for the government.
