In a statement on Tuesday, Iranian Foreign Ministry Spokeswoman Marziyeh Afkham voiced the Islamic Republic’s deep sorrow over “the tragic incident” and offered condolences to the bereaved families of the victims.
All 54 people on board a Trigana Air aircraft were killed in the crash, which happened two days ago in Indonesia's Papua province, Indonesian officials said on Tuesday.
Major-General Heronimus Guru, operations director at Indonesia's National Search and Rescue Agency, told a news conference in the capital the passengers' remains were being put into body bags but poor weather had hampered efforts to recover them by air.
Officials have declined to comment on the cause of Sunday's crash until the results of an investigation by the national transport safety committee are known, but Guru said the terrain in Indonesia's easternmost province may have been a factor, according to Reuters.
"There's a possibility the aircraft hit a peak and then fell into a ravine because the place that it was found in is steep," Guru said.
The treacherous terrain of forest-covered ridges hampered rescuers' efforts to reach the site where the Trigana Air Service ATR 42-300 plane came down.
The aircraft's black box flight recorder, which should provide investigators with some answers, was found in the early afternoon. The device will be taken to Oksibil town tomorrow, depending on the weather, Guru said.
