Erdogan: Biggest quake since 1939

Turkish President Recep Tayyip Erdogan said the earthquake was the strongest since 1939, when a 7.9 quake hit the eastern city of Erzincan and killed more than 30,000 people.

Erdogan said 9,000 personnel are carrying out search-and-rescue operations, a number constantly increasing as people try and access the affected areas.

Erdogan said: "As well as Nato and the European Union, we have received aid offers from 45 countries."
