The United Arab Emirates said a drone strike had triggered a fire near its nuclear power station on Sunday, calling the incident a "dangerous escalation",  BBC reported. 

Officials are investigating the source of the strike. The country's defence ministry said three drones had entered the UAE from the "western border direction".

While two were intercepted, the third drone struck an electrical generator "outside the inner perimeter" of the Barakah Nuclear Power Plant in Abu Dhabi, sparking a fire.
