Canadian investigators flying to Tehran on Monday will access the wreckage and black boxes from a Ukranian jetliner downed by a missile strike last week, officials said.

"We don't fully know what the scope of our investigation will be," Transportation Safety Board (TSB) chair Kathy Fox told a press conference.
