A fire broke out at a residential building in the Turkish capital Ankara but it has been brought under control, a Turkish official said on Tuesday, following reports on social media about a possible explosion.

Reuters reporters in Ankara could see the fire, which appeared to be in a small building. No loud explosion had been heard in the city, they said.

Tensions are running high in Turkey following last Friday's failed military coup and a series of purges the government has launched in state institutions against those it considers implicated.
