Dutch month-ahead gas futures, Europe's benchmark, jumped as high as 14.4% to 35.50 euros a megawatt-hour in Amsterdam late in the European session. EU Natgas prices bottomed at the start of the month at around 22 euros and have since risen 54%. 

Bloomberg said outages at major oil and gas facilities in Norway had been extended through mid-July and had been one of the catalysts for the surge in EU NatGas prices today.
