Protests turn ugly in Mexico City

Crowd storms National Palace as anger swells over 43 students' deaths

Protesters angry at the apparent massacre of 43 students tried to break into Mexico City's National Palace late on Saturday while others torched several trucks in the south of the country.

Thousands of people marched in the capital in the latest demonstration over a case that has repulsed the nation and triggered the biggest crisis of President Enrique Pena Nieto's administration.
