At least 224 people, including 117 in the capital, were killed by a powerful earthquake that rocked Mexico on Tuesday, the authorities have said.

One of the worst scenes was at the Enrique Rebsamen primary school on Mexico City's south side, whose three floors collapsed into one during the 7.1-magnitude quake, trapping students and teachers inside. Twenty-one children and four adults are thought to have been killed, said deputy Education Minister, Javier Trevino.

President Enrique Pena Nieto, who rushed to the site, warned that the toll could rise.

The destruction revived horrific memories in Mexico on the anniversary of another massive quake in 1985, the disaster-prone country's deadliest ever.
