Saudi prince visits UAE as new Khashoggi controversy swirls
Stay tuned with 24 News HD Android App
His visit, ahead of a Gulf summit, comes as French authorities check the identity of a man who was arrested in Paris on suspicion of playing a key role in Khashoggi's murder.
However, Saudi Arabia said the suspect was a victim of mistaken identity as his name, Khaled Alotaibi, is common in the kingdom.
A man named Khaled Alotaibi is one of the 26 on trial in absentia in Turkey for being part of the hit squad that carried out the Khashoggi murder. He has also been sanctioned by the US Treasury for his role in the killing.
The arrest was made at Paris's main airport just days after French President Emmanuel Macron met the Saudi crown prince in Riyadh, dismissing accusations that his visit was effectively condoning Khashoggi's murder.
Security was tight at Expo, where the lavish Saudi pavilion was closed to visitors and a small crowd of onlookers, including women in black robes, gathered outside.
Saudi songs, including one with the lyrics "Welcome Mohammed", were playing on the loudspeaker at Al Wasl Plaza, Expo's central venue.
"Saudi Arabia has been, and will always be a key regional player."
