Rescuers in Turkey pulled several people alive from collapsed buildings on Monday, a week after the country’s worst earthquake in modern history, but hopes of many more survivors were fading and criticism of the authorities grew, writes Reuters.

In hard-hit Kahramanmaras, rescuers were attempting to reach a grandmother, mother and daughter, all from one family, who appeared to have survived the 7.8 magnitude Feb. 6 quake and aftershock which killed more than 37,000 in Turkey and Syria.

But others were bracing for the inevitable scaling down of operations as low temperatures reduced the already slim chances of survival, with some Polish rescuers announcing they would leave on Wednesday.

In the shattered Syrian city of Aleppo, U.N. aid chief Martin Griffiths said the rescue phase was “coming to a close”, with the focus switching to shelter, food and schooling. Syrian President Bashar al-Assad had agreed to allow more U.N. aid to access the war-torn country from Turkey, diplomats said late Monday.

There were still glimmers of hope. A 13-year-old was pulled out alive after spending 182 hours under the rubble of a collapsed building in Turkey’s southern Hatay province on Monday, his head braced, and covered for warmth, before he was moved into an ambulance.

A young girl named Miray was recovered alive in the southeastern Turkish city of Adiyaman, officials said, while state broadcaster TRT Haber said a 10-year-old girl was rescued in Kahramanmaras. At least two other children and three adults were also reported to have been rescued.
