ANTAKYA, Turkey/JANDARIS, Syria (Reuters) -Rescuers in Turkey pulled more people from the rubble early on Saturday, five days after the country's most devastating earthquake since 1939, but hopes were fading in Turkey and Syria that many more survivors would be found.

In Kahramanmaras, close to the quake's epicentre in southern Turkey, there were fewer visible rescue operations amid the smashed concrete mounds of fallen houses and apartment blocks, while ever more trucks rumbled through the streets shipping out debris.

The growing death toll, exceeding 24,450 across southern Turkey and northwest Syria, raised questions over Turkey's earthquake planning and response time, and President Tayyip Erdogan said on Friday that authorities should have reacted faster.

Speaking on Saturday, Erdogan promised to start work on rebuilding cities "within weeks", saying hundreds of thousands of buildings were now uninhabitable, while issuing stern warnings against any people involved in looting in the quake zone.

In the rebel enclave of northwest Syria that suffered the country's worst damage from the earthquake but where relief efforts are complicated by the more than decade-old civil war, very little aid had entered even after the Damascus government said on Friday it would allow convoys to cross frontlines.

In Turkey, 67 people had been clawed from the rubble in the previous 24 hours, Turkish Vice President Fuat Oktay told reporters overnight, in efforts that drew in 31,000 rescuers across the affected region.

Overnight, a 70 year-old woman and a nine year-old boy were rescued in Kahramanmaras and a 55 year-old woman was pulled from the rubble in the eastern city of Diyarbakir. However, a woman who was rescued on Friday in Kirikhan in Turkey died in hospital on Saturday.

The danger in such operations was evident in a video filmed in Hatay in Turkey on Saturday, showing a partially collapsed building suddenly slipping and burying a rescuer in an avalanche of debris before his colleagues could haul him out.
