And just when oil was tapering off on hopes that the Middle East supply situation may actually normalize, we get this from The Guardian: "Saudi forces are preparing to intervene in neighbouring Bahrain, after a day of clashes between police and protesters who mounted the most serious challenge to the island's royal family since demonstrations began a month ago. The Crown Prince of Bahrain is expected to formally invite security forces from Saudi Arabia into his country today, as part of a request for support from other members of the six-member Gulf Co-operation Council." Pretty mich just as we predicted earlier. And yes, this is huge as Iran will promptly respond, setting off dormant religious tensions with a bang.
The crown prince, Salman bin Hamad al-Khalifa, said in a televised statement that Bahrain had "witnessed tragic events" during a month of unprecedented political unrest.
Warning that "the right to security and safety is above all else", he added: "Any legitimate claims must not be made at the expanse of security and stability."
The crown prince has also promised that national dialogue would look at increasing the power of Bahrain's parliament, and that any deal could be put to nationwide referendum.
However, some protesters have pressed their demands further to call for the toppling of the Sunni dynasty.
The unrest is being closely watched in Saudi Arabia, where Shia are some 15% of the population.
The secretary general of the Gulf Co-operation Council, Abdulrahman bin Hamad al-Attiya, expressed the "full solidarity with Bahrain's leadership and people", adding that "safeguarding security and stability in one country is a collective responsibility".
In an apparent reference to Iran, which Gulf Arab ruling elites fear may capitalise on an uprising by Shiites in Bahrain, he also expresssed "strong rejection of any foreign interference in the kingdom's internal affairs, asserting that any acts aiming to destabilise the kingdom and sow dissension between its citizens represent a dangerous encroachment on the whole GCC security and stability." Reports that the Saudi National Guard was poised to enter Bahrain were cited by the Foreign Office, alongside a recent increase in protests, as it changed its advice to advise British citizens against all travel to Bahrain.
Earlier on Sunday, police moved in on Pearl Square, a site of occupation by members of Bahrain's Shia majority, who are calling for an elected government and equality with Bahrain's Sunnis.
Witnesses said security forces surrounded the protesters' tent compound, shooting tear gas and rubber bullets at the activists in the largest effort to clear the square since a crackdown last month that left four dead after live ammunition was fired.
Activists tried to stand their ground yesterday and chanted "Peaceful, peaceful" as the crowd swelled into thousands, with protesters streaming to the square to reinforce the activists' lines, forcing the police to pull back by the early afternoon.
And with the headquarters of the US Fifth Fleet a cab ride away from the main square where demonstrations are about to be an hourly occurrence, the US may it rather hard to get involved.
