HOPES were fading for earthquake survivors trapped in the rubble in Turkey and Syria today as the death toll neared 20,000.
Turkish President Recep Erdogan admitted there have been "shortcomings" to rescue efforts since the devastating disaster, and experts have warned time is running out.
The official number of deaths from Monday's mega-quake reached 16,546 in Turkey and more than 3,000 in Syria.
The grim toll surpassed the 17,000 killed in a quake in northwest Turkey in 1999.
And experts warned the survival window for those still trapped under wrecked buildings is diminishing as the days go by.
