Several loud blasts heard, bright flashes seen in sky above Riyadh - Reuters witness

RIYADH (Reuters) - At least six loud blasts were heard and bright flashes were seen in the sky over Saudi Arabia's capital Riyadh on Sunday, and puffs of smoke were later visible above the city, a Reuters witness said.

There was no immediate comment from Saudi authorities or a Saudi-led coalition fighting in neighbouring Yemen against the armed Houthi movement, which has targeted Riyadh with ballistic missiles several times in recent months.
