Iranian officials called off rescue operations, saying there was little chance of finding more survivors from the earthquake that shook parts of western Iran on Sunday, killing at least 530 people, state media said on Tuesday.
Survivors, many left homeless by the 7.3 magnitude earthquake that struck villages and towns in a mountainous area bordering Iraq, battled overnight temperatures just above freezing and faced another bleak day on Tuesday in need of food and water.
The death toll of 530, reported by state news agency IRNA, made it Irans deadliest earthquake in more than a decade. Thousands of people were injured and 30,000 homes damaged. Two whole villages were destroyed.
The quake struck on the Iran-Iraq border, causing most of its damage in Iran despite an epicenter on the Iraq side of the frontier. Iraqi officials said seven people were killed and 325 injured in Iraq, all in the northern Kurdish provinces.
Iran's President Hassan Rouhani arrived in the morning in the stricken area in Kermanshah province and promised that the government would "use all its power to resolve the problems in the shortest time".
Thousands of people huddled in makeshift camps while many others chose to spend a second night in the open, despite low temperatures, because they feared more tremors after some 193 aftershocks, state television said.
