Turkish President Recep Tayyip Erdogan has announced a three-month state of emergency in 10 provinces worst-affected by an earthquake that has killed thousands.
Mr Erdogan said that the death toll in Turkey has risen to 3,549 people.
More than 1,600 people are reported to have died in Syria.
In a televised address, Mr Erdogan said the state of emergency is to ensure that rescue work can be “carried out quickly” in the country’s south-east.
He said the measures would allow relief workers and financial aid into the affected regions, but did not give further details.
The state of emergency will end just before elections on 14 May, when Mr Erdogan will attempt to stay in power after 20 years.
