TEHRAN, Jan. 14 (Xinhua) -- Iranian President Hassan Rouhani on Tuesday urged the Iranian Judiciary to form a "special court" to investigate further the recent crash of Ukrainian passenger plane over Tehran's sky.

"The Judiciary should establish a special court with a senior judge and tens of experts. This dossier (of Ukrainian plane crash) is not a common case. The world is looking at us," Rouhani said in a live broadcast from state TV.

Rouhani expressed his satisfaction with the "straightforward" announcement of the armed forces about their "mistake" over the plane crash, saying that it was the first step and the next steps should also be taken to clarify the dimensions of the incident.

He noted that the issue could not be blamed on a single person's error by pushing a button and hitting the plane. "There are others (involved in the incident) and I want it to be sincerely explained to the people," he stressed.

On Wednesday, a Ukrainian Boeing 737-800 passenger plane crashed near Tehran, and all of the 176 people onboard, including Canadian and Ukrainian passengers, were killed. Iran admitted that the plane was brought down due to "human error."
