The number of people known to have died in Syria and Turkey has surpassed 11,000 as rescue attempts continue for a third day.

Two earthquakes that struck on Monday have quickly become the deadliest in Turkey since 1999, when 17,000 died, and the number is expected to continue rising.

The World Health Organisation estimates the final figure will be closer to 20,000.

In a news conference moments ago, Turkish President Recep Tayyip Erdogan said 8,574 deaths have now been recorded in the country.

This morning The White Helmets volunteer rescue team tweeted more than 1,280 people had died in insurgent-held areas of Syria, with another 2,600 injured.

In government-controlled parts of the country, the death toll is 1,250, the Syrian health minister was reported to have said by the state-run al-Ikhbariya news outlet.

In total, at least 11,104 people have lost their lives.
