North Sea Brent crude oil futures jumped back above $100 a barrel on Monday on worries unrest in Egypt could spread to other parts of the Middle East and north Africa, disrupting energy supplies.

A senior Kuwait official said over the weekend oil prices could exceed $110 per barrel if the turmoil in Egypt continued, while Venezuela said prices could more than double to $200 if the Suez Canal closed.

Iran, which holds the rotating presidency of the Organization of the Petroleum Exporting Countries, said it saw no need for an emergency OPEC meeting even if oil prices hit $120.

'There is a lot of uncertainty over Egypt. We do not know what is going to happen there and the worry is that contagion will spread, destabilising other countries,' said Christophe Barret, oil analyst at French bank Credit Agricole.

'Of course everyone is worried -- the Middle East is such a big source of energy.'

Commerzbank analysts said oil prices remained 'well protected on the downside' 'on the back of continued protests in the Middle East'.

'The unrest in Egypt has also had an impact on the behaviour of speculative financial investors, who are increasingly betting on rising oil prices again amid the uncertainty about possible effects on oil supply,' Commerzbank said in its daily note.

ICE Brent crude oil futures for March rose $1.07 to a high of $100.90 before slipping back to around $100.50 by 1035 GMT. On Feb. 3, Brent reached an intra-day high of $103.37, its highest since September 2008.

US crude futures were more restrained as investors looked past the political crisis in Egypt and took note of high oil inventories, particularly in the US Midwest and Cushing, Oklahoma, the delivery point for the New York Mercantile Exchange's crude futures contracts.
