Rescuers ended the search on Sunday for survivors of twin earthquakes in northwestern Iran that killed at least 250 people and injured more than 2,600 a day earlier, state television reported.
At least 20 villages were totally leveled, state television reported. Ahmad Reza Shajiei, a senior government official in charge of rescue operations, said more than 5,000 tents have been set up to shelter more than 16,000 homeless. Thousands spent the night outdoors after their villages were leveled and homes damaged in the powerful quakes, which were followed by some 36 aftershocks.
Television video showed people being evacuated on stretchers, while others were treated for broken limbs and concussions. Dozens of families were sleeping on blankets laid out on the ground in parks. Some were crying, and others shivered from the cold in the mountainous region hit by the quake, near the border with Azerbaijan.
More than 1,100 rescuers worked through the night to pull out those trapped under rubble and to reach some of the more remote villages affected. Some 15 dogs were brought in to search for survivors.
By afternoon, state television reported that search operations had ceased. The government's attention shifted to providing shelter to the homeless and removing debris from the buildings destroyed.
The U.S. Geological Survey reported that Saturday's first quake at was magnitude 6.4 and struck 60 kilometers (35 miles) northeast of the city of Tabriz at a depth of 9.9 kilometers (6.2 miles). State TV quoted local Crisis Committee chief Khalil Saei as saying the epicenter was a region between the towns of Ahar and Haris, about 600 kilometers (350 miles) northwest of the capital Tehran.
The second quake was a magnitude 6.3 and struck 11 minutes later, the USGS reported. Its epicenter was 50 kilometers (30 miles) northeast of Tabriz at a depth of 9.8 kilometers (6.1 miles).
The quakes hit the towns of Ahar, Haris and Varzaqan in East Azerbaijan province, state television reported. In addition to 20 villages destroyed, more than 130 others sustained heavy damage, state TV said.
The aftershocks were felt in a wide region near the Caspian Sea, causing panic among the people.
Officials have announced two days of mourning in East Azerbaijan province.
Interior Minister Mostafa Mohammad Najjar said the government will allocate funds to rebuild the houses destroyed in the quake, aiming to complete the construction before the arrival of cold winter temperatures.
Najjar said the plans aim to construct buildings resistant to earthquake. Most of houses in rural areas are built of mud, and they can crumble when even a moderate quake hits.
Iran is located on seismic fault lines and is prone to earthquakes. It experiences at least one earthquake every day on average, although most are so small they go unnoticed. In 2003, some 26,000 people were killed by a magnitude 6.6 quake that flattened the historic southeastern city of Bam.
According to Najjar, several foreign countries have offered assistance, but he said Iran doesn't need outside help and can manage the situation. He did not name the countries.
