More than 8,700 people are known to have been killed in Turkey and Syria following Monday's earthquake.

The death toll in Turkey has risen to 6,234, according to the country's disaster agency.

It is difficult to verify the number in Syria, but its state media and a rescue group say more than 2,500 people have been killed.

A total of 1,250 people have died in the government-held region, said the Syrian health minister.

The White Helmet, which operates in the rebel-controlled area, say the death toll has risen to more than 1,280.
