ATLANTA - Atlanta's public transit system has increased its security measures in response to two suicide bomb attacks at subway stations in Russia.
MARTA said in a statement Monday that its police deparment is increasing the number of officers and patrols throughout the system.
Female suicide bombers blew themselves up Monday in twin attacks on Moscow subway stations, killing several dozen rush-hour passengers and wounding scores more.
The federal Department of Homeland Security has said there are currently no credible threats to transit systems in the U.S. But MARTA says its police force is operating on heightened alert to ensure the system's security.
MARTA asks everyone to report any suspicious behavior.
