Mexico's president says he is sending four more battalions to northern Mexico, where forces are engaged in a bloody battle with drug smugglers.
President Felipe Calderon said Saturday that the soldiers will be deployed to the state of Tamaulipas, along Mexico's border with the United States. He said he was also going to send new armored vehicles and bullet-proof vests. And he pledged to raise salaries for soldiers and increase pensions for the widows of slain soldiers.
