An 18-year-old man has been pulled from the rubble of a building in southern Türkiye, some 198 hours after the country's devastating earthquake

Rescuers again worked through the night to rescue people clinging to life.

But some teams have started scaling back operations as low temperatures reduced the already slim chances of survival.

Some Polish rescuers, among many multinational teams that flew in, have announced they would leave on Wednesday.

Earlier on Tuesday, a boy and a man were saved in hard-hit Kahramanmaraş, while rescuers were still trying to reach a grandmother, mother and daughter from one family who appeared to have survived in the broken masonry of a building.

In the shattered Syrian city of Aleppo, UN aid chief Martin Griffiths said the rescue phase was "coming to a close", with the focus switching to shelter, food and schooling.

Syria's President Bashar al-Assad had agreed to allow more UN aid to access the war-torn country from Türkiye, diplomats said late on Monday.

Turkish media said rescuers held out hope of finding survivors at several locations in Kahramanmaraş province, Adiyaman and Hatay, where there were signs of life beneath the ruins.

But in the southern city of Antakya, excavators began tearing down heavily damaged buildings and clearing rubble.

Blue lights from ambulances lit up the dim streets where there was still no power and the smell of smoke filled the air.

Hundreds of people are leaving the city every day, and those who remain huddle around fires on street corners and in parks, and sleep in tents or cars.

As they worked through the night, rescue workers occasionally called for silence as they listened for the faintest sound of life from under the rubble
