Saudi Arabia’s crown prince blamed Iran for attacks on two oil tankers in the Gulf of Oman and called on the international community to take a “decisive stand”, but said that the kingdom does not want a war in the region.

Attacks on two oil tankers on Thursday, which the United States also blamed on Iran, have raised fears of broader confrontation in the region. Iran has denied any role in the strikes south of the Strait of Hormuz, a vital shipping route and major transit route for oil.

Security forces in Central African Republic beat and detained two journalists working for French news wire Agence France-Presse (AFP) covering a banned opposition protest in the capital Bangui, the reporters said Sunday.

Charles Bouessel, 28, and Florent Vergnes, 30, said they were held for more than six hours and questioned three times on Saturday after having been manhandled by members of the Central Office for the Suppression of Banditry (OCRB).

The pair also had their equipment confiscated and a camera smashed up.

AFP condemned the incident as "unjustifiable police violence".

Throngs of largely black-clad protesters snaked their way for miles through the streets to the city's parliament -- with the organisers' estimate for the crowd size doubling an already record-breaking demonstration the previous Sunday in the city of 7.3 million.
