Riyadh - Saudi King Salman accused Syrian President Bashar al-Assad on Wednesday of having aided the rise of the Islamic State group and called for a political settlement with moderate forces to end the war.
The solution would be to form "a transitional government made up of moderate opposition forces, ensuring the unity of Syrians and the departure of foreign forces and terrorist organisations," the king said in an annual speech to the consultative Shura Council.
These organisations "could not have found fertile ground in Syria, had it not been for the Syrian regime's policies, which have exterminated hundreds of thousands... and displaced millions" of people, said the monarch.

More than 250 000 people have been killed in Syria since the conflict broke out in March 2011.
The kingdom, a key-backer of Syrian opposition groups, has repeatedly insisted on Assad's departure.
Earlier this month, Riyadh hosted a meeting of various Syrian armed and political opposition groups who agreed to negotiate with the regime but set Assad's departure as a condition for any eventual political transition process.
