Turkish authorities have arrested or detained a number of property developers as the death toll from last week’s catastrophic earthquake soared past 36,000.

The 7.8-magnitude quake that struck southeastern Turkey near the border with Syria last Monday has now caused 31,643 deaths in Turkey, according to the Turkish Emergency Coordination Center SAKOM on Monday. The number of dead in Syria now stands at 4,574, state media said Sunday.

Last week’s earthquake will likely become Turkey’s deadliest – a 1939 quake killed 32,962 people.

Emergency responders have been frantically working to reach residents trapped beneath the rubble in Turkey. In northwest Syria, rescue operations have now ended, the White Helmets volunteer organization said.

As families mourn the loss of loved ones, resentment has grown among those affected and many are now looking to assign blame for the extent of the disaster.
