Turkish President Recep Tayyip Erdogan is in the earthquake disaster zone in his country as criticism grows over the official response.

Families in some badly-hit areas have said the slow speed of rescue efforts means they have had no help digging through ruins to find relatives.

Erdogan acknowledged there'd been difficulties with the initial response but blamed delays on damaged roads and airports.

"We survived the earthquake, but we will die here due to hunger or cold," said a 64-year-old in Antakya, Hatay province.

More than 11,000 people in southern Turkey and northern Syria are now known to have been killed.

The White Helmets, who are leading efforts to rescue people in rebel-held areas Syria, say time is running out to save people.

Dramatic footage has emerged of rescues - one family of six were pulled alive from the rubble in the Syrian city of Idlib.
