A debate about possible US military intervention in Mexico ended in a scene of violence in the Senate, when Pri leader Alejandro Moreno was involved in a physical confrontation with the mayor, Gerardo Fernández Noroña of the Morena party.
A Mexican Senate session fell on violence on Wednesday after one of its members apparently became enraged that he had no opportunity to speak.
The altercation took place between two high -level senators, near the end of a session that included a heated debate on the possibility of US military intervention in the country.
While the national anthem was being touched, Senator Alejandro Moreno-president of the Pri opposition party-headed for the pulpit and grasped the Senate’s president, Gerardo Fernández Noroña of the party in brunette power, starting a physical confrontation.
Other gifts intervened next. A broadcast live shows a man really trying to unravel a punch in Noroña, while Moreno pushes another man with a green shirt, to the floor.
Noroña later identified this man as a member of his team. He appeared next to Noroña at a press conference with a cervical necklace and bandage on his arm.
Moreno stated on social networks that he had confronted Noroña because the party in power had altered the session agenda to prevent the opposition from pronouncement.
“This cowardice provoked what followed. Let it be clear: the first physical aggression came from Noroña,” he said, claiming that the president of the Senate began the altercation by pushing him.

For his part, Noroña insisted that the opposition senators were responsible. “They came together against me. They will say this is freedom of expression,” he said.
He also said that during the session they had discussed topics such as US military intervention, which accused the opposition parties to support.
He also added that he intended to file a complaint against Moreno, claiming that he threatened him with death, and that he would still propose the expulsion of Moreno and other members of the opposition involved in the altercation.
CNN contacted Moreno to get a reaction.
Violence in the Mexican Congress is rare but not unprecedented.
In 2006, a fight snapped among deputies before the inauguration of President Felipe Calderón, after a contested election.
