Violence breaks out at meeting with lawmakers

CHACO, Argentina First voices were raised and then plastic chairs went flying, then anything that wasn't tacked down was thrown at the opposition.

Both sides took refuge in opposite sides of the room and that's when fully geared-up riot police took position in the middle of the room to restore order and separate the groups. Both sides then broke into chants.

The lawmakers were trying to pick the president of a northern province. At least 10 legislators were slightly injured during the chaos.

Chaco is north of the capitol, Buenos Aires.
