MEXICO CITY, Feb. 11 (Xinhua) -- Mexican authorities have rescued 229 migrants and arrested six suspected people smugglers in the northern state of Tamaulipas, authorities announced on Sunday.

The Tamaulipas coordination group, made up of the army and federal and state security forces, said in a statement that the migrants were found in six safehouses, waiting to cross into the U.S.

Of those rescued, 128 were from Guatemala, 86 from Honduras, 11 from El Salvador, 3 from Nicaragua and 1 from Mexico. They included 109 children and 120 adults, including 41 women.
