Macedonian authorities say an explosion in a gas plant near the border with Greece has killed at least three workers and injured two others.
Nadica V'ckova, spokeswoman for the national center for crisis management, said the explosion occurred in a department where gas cylinders were being filled early Thursday in the plant in the southern town of Bogdanci.
Firefighters were trying to contain the blaze that broke out after the explosion. Police and public prosecutors were investigating what caused the blast.
Local media said one of the injured workers was transferred to a clinic in the capital Skopje to be treated for severe burns.
