Iran state TV says rescue operations have ended in quake-hit areas

"The rescue operations in the (western) Kermanshah province have ended," Pir-Hossein Kolivand, head of Iran's Emergency Medical Services, said on state TV.

Sunday's 7.3-magnitude earthquake struck villages and towns in the mountainous area of Kermanshah province that borders Iraq while many people were at home asleep. At least 14 provinces in Iran were affected.

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.

"It is a very cold night... we need help. We need everything. The authorities should speed up their help," she said.

Iran's top authority Supreme Leader Ayatollah Ali Khamenei offered his condolences on Monday and called on government agencies to do all they could to help those affected.

Iranian police, the elite Revolutionary Guards and its affiliated Basij militia forces were dispatched to affected areas on Sunday night. President Hassan Rouhani will visit the area on Tuesday, state TV said.

Television showed footage of rescue workers frantically combing through the rubble of dozens of villages immediately after the quake. But Iranian officials said the chances of finding any more survivors were extremely low.
