Turkish officials have issued arrest warrants for more than 130 people allegedly involved in shoddy and illegal construction methods.
Thousands of buildings collapsed after earthquakes hit southeastern Turkey and northern Syria on Monday.
The death toll stands at 28,191 with another 80,000 injured. The search for survivors continued on Sunday.
Warrants have been issued for the detention of 131 people suspected of being responsible for collapsed buildings, Turkish Vice President Fuat Oktay said on Saturday.
Even though Turkey has, on paper, construction codes that meet current earthquake-engineering standards, they are too rarely enforced, explaining why thousands of buildings slumped onto their side or pancaked downward onto residents.
Turkey’s justice minister has vowed to punish anyone responsible, and prosecutors have begun gathering samples of buildings for evidence on materials used in constructions.
Authorities at Istanbul Airport on Sunday detained two contractors held responsible for the destruction of several buildings in Adiyaman.
The pair were reportedly on their way to Georgia.
One of the arrested contractors, Yavuz Karakus said: “My conscience is clear. I built 44 buildings. Four of them were demolished. I did everything according to the rules.”
Two more people were arrested in the province of Gaziantep suspected of having cut down columns to make extra room in a building that collapsed.A day earlier, Turkey’s Justice Ministry announced the planned establishment of “Earthquake Crimes Investigation” bureaus.
The bureaus would aim to identify contractors and others responsible for building works, gather evidence, instruct experts including architects, geologists and engineers, and check building permits and occupation permits.
A building contractor was detained by authorities on Friday at Istanbul airport before he could board a flight out of the country.
He was the contractor of a luxury 12-story building in the historic city of Antakya, in Hatay province, the collapse of which left an untold number of dead.
The detentions could help direct public anger toward builders and contractors, deflecting attention away from local and state officials who allowed the apparently sub-standard constructions to go ahead.
Turkish President Recep Tayyip Erdogan’s government, already burdened by an economic downturn and high inflation, faces parliamentary and presidential elections in May.
Survivors, many of whom lost loved ones, have turned their frustration and anger also at authorities. Rescue crews have been overwhelmed by the widespread damage which has impacted roads and airports, making it even more difficult to race against the clock.
Erdogan acknowledged earlier in the week that the initial response has been hampered by the extensive damage.
He said the worst-affected area was 500 kilometers (310 miles) in diameter and was home to 13.5 million people in Turkey.
During a tour of quake-damaged cities Saturday, Erdogan said a disaster of this scope was rare, and again referred to it as the “disaster of the century.”
Rescuers, including crews from other countries, continued to probe the rubble in hope of finding additional survivors who could yet beat the increasingly long odds.
Thermal cameras were used to probe the piles of concrete and metal, while rescuers demanded silence so that they could hear the voices of the trapped.
