Hundreds of thousands of people still need adequate shelter and sanitation a month after a huge earthquake devastated parts of Turkey and Syria, a United Nations official said.

An appeal for a billion US dollars (£832 million) is only 10% funded, hampering efforts to tackle the humanitarian crisis, they added.
