Havana, Cuba (CNN)Two weeks after the United States and Cuba agreed to thaw decades of icy relations, the U.S. State Department blasted the Cuban government for reportedly arresting at least six dissidents. There was no comment from Cuban authorities on the arrests that were reported by other dissidents and the U.S. State Department. "We are deeply concerned about the latest reports of detentions and arrests by Cuban authorities of peaceful civil society members and activists," State Department spokesman Jeff Rathke said in a statement. Roberta Jacobson, the assistant secretary of state for Western Hemisphere Affairs, wrote Tuesday on Twitter that "Freedom of expression remains core of U.S. policy on ‪Cuba, we support activists exercising those rights and condemn today's detentions."
