RIGA, April 15 (LETA) - Large rescue sources were involved in tracking down the source of an unidentified smell spreading in the area of Krustpils Street in Riga on Monday, LETA was told at the State Fire and Rescue Service.

Shortly after 3 p.m., rescuers were called to Krustpils Street in Riga where an odor of an unidentified substance could be felt in the air. The nearby building of a manufacturing company was evacuated due to the strong stench.
