Iranian authorities say rescue operations have ended in areas hit by a powerful earthquake near the border with Iraq that killed at least 450 people and injured more than 7,000 others.

The magnitude-7.3 earthquake struck villages and towns in the mountainous area of Kermanshah province on Sunday night (local time) while many people were at home asleep.

Television showed footage of rescue workers frantically combing through the rubble of dozens of villages immediately after the quake. But authorities say it is highly unlikely anyone else will be found alive. “The rescue operations in the [western] Kermanshah province have ended,” Pir-Hossein Kolivand, head of Iran’s Emergency Medical Services, said on state TV, as reported by ABC News.

Iranian officials said more than 450 people were killed and some 7,156 were injured when the earthquake jolted the country, affecting at least 14 provinces in Iran. Local officials expect the death toll to climb as teams reach remote areas.

State television said thousands were huddling in makeshift camps while many others spent a second night in the open for fear of more tremors to come after some 193 aftershocks.

A homeless young woman in Sarpol-e Zahab, one of the hardest-hit towns, told state TV that her family was exposed to the night chill because of lack of tents.

More than 70,000 people needed emergency shelter, the head of Iranian Red Crescent said. On Sunday night, Iranian police, the elite Revolutionary Guards and its affiliated Basij militia forces, were dispatched to affected areas. President Hassan Rouhani will visit the area today.

Across the border, there was still no word from Iraqi Kurdistan on whether their rescue missions were ongoing.
