YEREVAN, APRIL 2, ARMENPRESS. The preliminary suspected cause of the Burger King restaurant explosion in Yerevan’s Northern Avenue is the blast of a pressure oxygen cylinder of draught beer keg.

The preliminary cause was announced by Davit Tonoyan, minister of emergency situations of Armenia, who personally visited the scene of the blast. The minister went inside the restaurant and viewed the area.

The minister didn’t mention other details of the probable cause, adding that investigators and technical security experts are looking into it.
