MOSCOW (Reuters) - Russian troops have blown up a natural gas pipeline in the Ukrainian city of Kharkiv, Ukraine's state service of special communications and information protection said on Sunday.

       A mushroom-shaped explosion was shown in a video it posted on the Telegram messaging app.

       It was not immediately clear how important the pipeline was and whether the blast could disrupt gas shipments outside the city or the country. Despite the war, Ukraine continues to ship Russian natural gas to Europe.
