Iran makes arrests over downing of Ukrainian jet

Iran has announced several arrests in connection with last week's downing of a Ukrainian airliner.

The passenger jet crashed shortly after takeoff from Iran's capital Tehran last Wednesday, killing all 176 people on board. It occurred hours after Iran fired missiles at Iraqi bases hosting US-led coalition forces.

Iran initially denied involvement but admitted last Saturday to accidentally shooting down the plane and began accepting investigators from Ukraine and Canada.

Iran's state-run news agency on Tuesday quoted an Iranian judiciary spokesperson as saying that some individuals have been arrested and investigations are continuing.

The spokesperson did not say how many were arrested or who.

Iranian President Hassan Rouhani stressed that the responsibility falls on more than just one person, and urged the judiciary to set up a special court for the case.

Many Iranians, upset that the crash killed so many of their own, have taken to the streets to protest what they see as an attempted cover-up by the country's leaders.

The arrests appears to underscore Iran's determination to deal firmly with the matter.
