DUBAI, Jan 11 — The Ukrainian plane crash earlier this week was caused by human error and "US adventurism”, Iranian Foreign Minister Mohammad Javad Zarif said in a tweet today.

"A sad day. Preliminary conclusions of internal investigation by Armed Forces: Human error at time of crisis caused by US adventurism led to disaster,” Zarif wrote on Twitter. "Our profound regrets, apologies and condolences to our people, to the families of all victims, and to other affected nations.” — Reuters
