A strong quake with a magnitude of 6.2 has hit Indonesia's Lombok island, causing buildings to collapse, according to witnesses and the Southeast Asian nation's meteorology and geophysics agency.
Sunday's natural disaster triggered at least 230 aftershocks, which were expected to continue for the next two weeks.
Indonesia's top security minister, Wiranto, says the death toll from last Sunday's natural disaster on the island of Lombok has climbed to 319.
Some 4,600 tourists have been evacuated from the Gili Islands, three tiny, coral-fringed tropical islands off the northwest coast of Lombok which are popular with backpackers and divers.
This is the terrifying moment a shaking building suddenly collapses in Lombok after the Indonesian island was rocked by its third major quake in just 12 days.
Officials said the epicenter of the aftershock was on land and so there was no risk of a tsunami.
The strong aftershock, measured at magnitude 5.9 by the U.S. Geological Survey, caused panic and damage. "I was in the hospital, and my (unborn) child was gone", Handayani said, weeping as she told her story Friday in a green tent set up to house patients because it was considered unsafe to treat them inside.More news: Mayfield to play 2 quarters in preseason opener

BNPB's toll of verified deaths from Sunday's 6.9 magnitude quake was raised on Thursday to 259 from 131.
However, he said today the "death toll has jumped significantly", without providing further details. Since Sunday more than 350 aftershocks have kept survivors in a state of anxiety.
Spokesman Arifin Hadi said people need clean water and tarpaulins most of all. "It forced us back to this (tented) shelter again", he said.
Evacuees in some encampments say they are running out of food, while others are suffering psychological trauma after the powerful quake, which struck just one week after another tremor surged through the island and killed 17.
