At least 56 people were killed in an earthquake that rattled Indonesia’s main island of Java on Monday, the governor of the worst-hit province said.

“Data from the district head team — 56 people died and more than 700 injured. Because there are still a lot of people trapped on the scene, we assume injuries and fatalities will increase over time,” West Java governor Ridwan Kamil told a news conference broadcast by Kompas TV.
