At least 10 people were killed and 20 others injured Wednesday when a bus flipped over on a highway in the northwestern Venezuelan state of Lara, the Interior Ministry said.

"So far, they are reporting 10 people dead and 20 injured to us in the rollover on the Carora-Barquisimeto highway," Interior Ministry public affairs chief Jorge Galindo said in a Twitter posting.

The cause of the accident involving the Aeronasa lines bus has not been determined, Galindo said.

The injured were taken to hospitals in the nearby cities of Quibor and Carora, the official said. EFE
