All 66 people on board are believed to have been killed when a passenger plane crashed in Iran on Sunday. "This plane had 60 passengers, 59 adults, and one child, as well as a pilot, a co-pilot, two flight attendants and two air marshals on board". "We do not know anything about the crash", Iran's Minister of Roads and Urban Development Abbas Akhoundi reportedly told Tasnim News Agency on arrival in Semirom.
"The bodies must be transferred by hand to the foot of the mountain, which will be time-consuming", he said.
In a letter dated Feb 20 and addressed to Iran's President Rouhani, President Halimah said that she was "saddened" to learn about the "tragic crash".
Some of the bodies are recognizable and some are not.
On Tuesday, Isfahan Province emergency center said that a mobile phone of the passengers had transmitted signals from a location near Mount Dena where helicopters did not manage to reach the previous day due to bad weather, Press TV reported.
Iran has suffered multiple aviation disasters, most recently in 2014 when 39 people were killed as a Sepahan Airlines plane crashed just after take-off from Tehran, narrowly avoiding many more deaths when it plummeted near a busy market.
The aircraft that crashed, an Aseman Airlines flight, was 24 years old.

But a YPG official and a pro-Assad military commander denied similar Turkish statements on Tuesday night. Turkey and the Syrian militias it supports tried to force them back with artillery fire.
The Aseman Airlines ATR-72, a twin-engine turboprop used for short-distance regional flying, crashed near its destination of the southern Iranian city of Yasuj, some 780 kilometers, or 485 miles, south of the Iranian capital, Tehran. It also flies internationally, but has been banned in the European Union over safety concerns.
Aseman Airlines has undergone other significant crashes with fatalities as well.
A helicopter sent by Iran's national emergency services was unable to land at the site of the accident due to severe weather, its spokesman said.
Decades of global sanctions have left Iran with an ageing fleet of passenger planes which it has struggled to maintain and modernise.
The US has maintained its own sanctions on Iran, which block nearly all trade with the country, but plane manufacturers were given a specific exemption under the nuclear deal.
In 2015, the country signed a nuclear deal with six world powers (Germany, United Kingdom, France, Russia, China and the United States), based on which Iran agreed to curb its nuclear-related activities in return for the easing of some sanctions against the country.
