The European Parliament held a minute's silence today for the victims of three incidents at the start of its plenary session in Brussels, BTA reported.
Parliament president Roberta Metsola called the minute for those killed in yesterday's crash on the Trakia motorway, the victims of the shooting in Krakow and those who died in the train crash in Spain.
"On behalf of the European Parliament, we offer our deepest condolences to the families and loved ones of those who died," Metsola said.
She thanked the rescuers and medics who worked at the crash site, and all blood donors.
Outside the EU institutions in Brussels and Strasbourg, EU and Bulgarian flags are flying at half-mast today in sympathy with the day of mourning declared in Bulgaria.
The plenary session runs for two days.
