RUSSIA UPS SECURITY AMID ALERT !

Three metro bombs killed 50 people in 2004. Russia has increased security in cities around the country after its intelligence chief warned of a terrorist attack on public transport.
Phone operators in Moscow have also switched off signals in the metro in an apparent attempt to stop mobiles being used to detonate explosives.
Russian TV has been broadcasting alerts throughout the day.
It is highly unusual for Moscow to issue statements on terrorist threats, says the BBC's Richard Galpin there.
No details
Late on Tuesday, the head of the Federal Security Service (FSB) announced foreign intelligence had indicated an attack was being planned.
Nikolai Patrushev gave no further details on the origin or nature of the information.
But officials have moved to assure the public that all is being done to tighten security around key civilian, government and military facilities.
Extra police have been deployed in all of the country's major cities, with an increased presence on the underground and train stations as well as airports.
The last major attack on Moscow's metro system was three years ago, when two bombs killed more than 50 people.
The authorities blamed that attack on Chechen rebels. Russia has for 12 years fought a bloody campaign to suppress an insurgency in the region.
