Heavy gunfire has been heard near the royal palace in Saudi Arabia's capital, Riyadh.

The official spokesman of district police in Riyadh said on Saturday that security forces "dealt with" an unauthorised, small drone-type toy after spotting it at a security point in al-Khuzami neighbourhood, state-run news agency SPA said.

The authorities opened an investigation into the incident, he added.

Videos posted online purportedly from the area showed heavy gunfire.
