At least one person was killed and two were injured on Thursday in a blast and fire at a building belonging to the border patrol of Russia's FSB security service in the southern city of Rostov-on-Don, according to local officials quoted by Russian news agencies.

Footage captured by Reuters showed a plume of thick black smoke billowing into the air, near residential buildings and a shopping centre in a built-up district of the city. Rostov Governor Vasily Golubev said the fire appeared to have been caused by an electrical short-circuit.

"The spread of fire caused containers of fuel and lubricants to explode," he said in a message posted on his Telegram channel. Nearby buildings were evacuated and authorities opened an investigation, Golubev said, adding that the fire had spread to an area of more than 800 sq metres.
