Saudi Arabia has long been the dominant force in oil, leaving the world at the mercy of its ambitions and its interests. Now the kingdom must refresh its strategy to reflect a weaker hand -- and in many ways, a different game.

Congress has released previously classified documents about whether the Saudi government had a role in the 9/11 attacks. The pages show no officials links between the Saudi government and the hijackers who killed nearly 3,000 people in New York. However, the report found it was likely that the attackers had financial help from people inside the kingdom. An independent panel completed the 9/11 Commission Report in 2002. But several pages - informally known as "the 28 Pages" - were withheld from the public for 13 years, fuelling speculation about their contents.

Mnuchin said on Sunday Saudi Arabia's explanation of the killing of journalist Jamal Khashoggi was a "good first step but not enough", adding that it was premature to discuss sanctions against Riyadh over the incident.

Riyadh on Sunday froze new trade with Canada and expelled the Canadian ambassador. It also ended state-backed educational and medical programs in a dispute that was sparked by Canada demanding the release of jailed rights activists.

DUBAI (Reuters) - Senior Saudi Prince Miteb bin Abdullah, once seen as a leading contender to the throne, was freed after reaching an "acceptable settlement agreement" with authorities paying more than $1 billion, a Saudi official said on Wednesday.
