The Brent oil price took off last night as Turkey shot down a Russian fighter, from the FT:
Vladimir Putin has accused the Turkish government of providing financial and military support to Isis, in a furious response to the downing of a Russian fighter jet near the Syria-Turkey border.
Turkey said it shot down the Russian Sukhoi Su-24 on Tuesday morning after it violated Turkish airspace, escalating tensions between international powers with competing aims in war-torn Syria.
