The United States welcomed Sunday the release of a former US Marine who had been held for several weeks by leftist rebels in Colombia.

"We welcome the release today of Kevin Scott Sutay from captivity at the hands of the FARC," Secretary of State John Kerry said in a statement. "The United States is profoundly grateful to the government of Colombia and commends its tireless efforts to secure his release. We offer special thanks to President Juan Manuel Santos for his assistance."
