Indonesia's West Papua province was hit by a magnitude 6.1 earthquake today, the latest powerful tremor to shake the region where five people were killed and hundreds injured at the weekend when buildings were destroyed.

The quake struck off the coast at 7:48 a.m. local time, 75 kilometers (50 miles) west of the region's main city of Manokwari, the U.S. Geological Survey said in an alert. There were no immediate reports of damage or casualties and no tsunami alert was issued.
