Six children were killed and 14 others trapped after a mosque in Indonesia collapsed on Tuesday during a Koran reading session when a powerful earthquake struck, an official said.
"Six children were found dead under the rubble of a mosque flattened by the quake," the head of the disaster management agency in central Aceh district, Subhan Sahara, told AFP.
"Our search and rescue are struggling to evacuate an estimated 14 children still trapped under the rubble.
"I hope they can be found alive but the chances are very slim."
The six deaths take the confirmed toll from the 6.1-magnitude quake in Aceh province, on Sumatra island, to 11.
Dozens more have been injured by the quake which struck at a shallow depth of just 10 kilometres (6.2 miles), and also caused many houses to collapse.
