A fire broke out at an administrative building in downtown Moscow in the early hours of Thursday, a local police source said.

The fire that engulfed the two-storey building at Pushkinskaya Square, within walking distance of the Kremlin, reportedly covered between 50 and 100 square meters.

"The fire has been put out, no one has been killed or injured," the source said, adding that the cause of the fire is being investigated.

Moscow has seen record high temperatures for over a month. Ten temperature records have already been broken and each day the temperature is nearing 40 degrees Celsius (104 degrees Fahrenheit). The heat wave in Russia has caused a number of fires, including peat bog fires, creating heavy smog throughout Moscow and the neighboring regions.
