Iran announced Tuesday its first arrests over the accidental shooting down of a Ukrainian passenger jet, as protesters vented their anger over the catastrophic blunder for a fourth consecutive day. Making matters worse for the sanctions-hit country, Britain, France and Germany triggered a dispute resolution mechanism under the already tattered 2015 nuclear deal, prompting Iran to warn them of unspecified “consequences”. The Ukraine International Airlines plane was brought down by a missile shortly after takeoff on Wednesday, killing all 176 passengers and crew on board.
