At least six people were killed after a magnitude-6.0 earthquake with a depth of 70 kilometers struck off the coast of Java Island, Indonesia on Saturday, said the country's disaster agency. 

"The agency has recorded six deaths, and one person sustained serious injuries," said National Disaster Management Agency Spokesperson Raditya Jati, adding that several villages in East Java had been evacuated.

It was not clear if the toll would rise, but the agency did not report anyone missing after the tremors.
