An Argentine commuter train slammed into the end of the line at the same station in Buenos Aires where 52 people were killed in a similar crash last year.

President Cristina Fernandez was re-elected in a landslide, winning with the widest victory margin in Argentina’s history after her government spread the wealth of a booming economy.

Fires said to have been started by farmers sent clouds of smoke across Argentina’s capital, disrupting air and road travel and choking residents.
