Mexico Violence Feared

TIXTLA, Mexico, () -- Mexico's army braced for fresh attacks on Friday after leftist guerrillas launched surprise attacks, killing at least 12 people in Mexico's worst political violence in more than two years.

Troops were on alert throughout Mexico and airports and ports stepped up security following ambushes by the self-styled Popular Revolutionary Army in three Mexican states late on Wednesday and early on Thursday, officials and news reports said.

Hundreds of masked, heavily-armed guerrillas stormed small villages in southern and central Mexico and attacked police and military posts. About 22 people were injured in the fighting, the most serious rebel activity since the Zapatista rebellion erupted in early 1994 in the southeastern state of Chiapas.
