Nieto Sworn in as President While Mexicans Riot

Enrique Pena Nieto was sworn into office, Saturday, as the new President of Mexico.

With him, the PRI has regained control of the country, after losing it in 2000, after holding it for most of the twentieth century.

Thousands of Mexicans rioted in the streets, protesting against Nieto's swearing in and the PRI's return.

They accuse the PRI of using bribery and intimidation to win the election.

Dozens were injured when the rioters clashed with police.

Rioters threw gas and alcohol bombs at riot police who responded with tear gas and rubber bullets.
