Thousands of Iranians have spent a second night outdoors in near-freezing temperatures after a devastating earthquake hit the west of the country.
The government is scrambling to get aid to the worst-hit area in the mountainous province of Kermanshah, where hundreds of homes were destroyed.
More than 400 people were killed and about 7,000 injured when the quake hit near the Iran-Iraq border on Sunday.
Iran has declared Tuesday a national day of mourning.
President Hassan Rouhani is due to visit the region.
Iranian officials said 413 people had died in the country. In the more sparsely populated areas across the border in Iraq, officials said nine people had died and several hundred were injured.
Iranian state TV said thousands of survivors were spending another night in makeshift camps or in the open. Many whose homes were still intact were frightened of returning because of dozens of aftershocks.
