Brent crude rose to $106.01 today, marking its seventh successive rise this week and it’s highest peak since 30 May, as supply disruptions continued with bombings in Syria and an attack on Israeli tourists in Bulgaria.

Six Israeli tourists were killed in a bomb attack in Bulgaria when travelling from an airport on Wednesday, with Isreal accusing Tehran of carrying out the attack, reports Reuters.

On the same day, a bomber killed and wounded Syrian President Bashar al-Assad’s security chiefs.

Oil prices, including US crude which rose by 76 cents to $90.62, were also supported by positive comments made by Federal Reserve Bank chief Ben Bernanke, which removed fears of a double-dip recession in the US.

Further gains were capped by data from the Energy Information Administration showing crude stocks in the US fell less than expected last week.
