CIUDAD JUAREZ, Mexico (AP) — Hundreds of people blocked bridges to the United States in three border cities Tuesday, demanding the army leave in another challenge for the Mexican government as it struggles to quell escalating drug violence. The protests in Ciudad Juarez blocked traffic for at least an hour across three bridges connecting the city to El Paso, Texas. Similar protests broke out on bridges in the border cities of Nuevo Laredo and Reynosa, while demonstrators blocked roads in the northern industrial city of Monterrey and the Gulf state of Veracruz.–Contact The Daily Reveille’s news staff at [email protected]
