Lombok quake death toll rises to 98

The death toll from a 6.9 magnitude earthquake that struck Indonesia's island of Lombok has risen to 98, a disaster official says.

The death toll from the Lombok earthquake has risen to 98 from the previously announced 91, National Disaster Mitigation Agency spokesman Sutopo Purwo Nugroho says.

Officials have been saying the number of deaths would increase as rescuers reach cut-off areas in north Lombok.

The 6.9 magnitude quake struck early on Sunday evening and also shook the adjacent island of Bali.

The ruins of a mosque that collapsed in Lading-Lading village on Lombok while people prayed inside was being pulled apart by a backhoe in search of victims.

Photos and video from the disaster agency showed Sunday's night quake had reduced the mosque to a mound of rubble.

So far no Australians have been reported hurt in the quake.
