Here is the report from SkyNews
Terrorists could be in the final stages of planning an attack on Saudi Arabia, the Foreign Office has warned.
It has issued fresh guidance to travellers about the possibility of an imminent attack.
The advice comes after British Airways cancelled flight Monday's BA 263 to Riyadh for security reasons.
The Foreign Office has already advised British nationals against all non-essential travel to Saudi Arabia.
Terrorists carried out attacks in Riyadh twice last year.
On November 9 they attacked the Muhayya residential compound in Riyadh killing 18 and injuring more than 80.
That followed coordinated bomb attacks against residential compounds in Riyadh on May 12, which killed more than 30 people, including two British
nationals, and injured many others.
The updated advice from the Foreign Office states: "We believe that terrorists remain determined to carry out further attacks in Saudi Arabia, and
that these may be in the final stages of preparation."
