Thousands of grieving Iranians gathered in Tehran Thursday for a mass funeral for more than 100 people killed this week in the crash of a military transport plane.
Mourners at Tehran's main cemetery, Behesht-e Zahra heard the parliament speaker Gholam Ali Haddad Adel promise a full government probe of the crash.
A separate judiciary investigation was announced Wednesday, after relatives of passengers said they were told by cell phone before take-off Tuesday that the pilot refused to fly because of safety problems.
One relative said her journalist spouse told her the C-130 plane sat on a runway for three hours because the pilot refused to fly.
Iran's military has denied the allegations, as well as reports that the first pilot was replaced after refusing orders to take off.
Authorities now say at least 108 people - including all 94 aboard the plane - were killed when the plane crashed into an apartment building in Tehran.
