London, Sep 16 (IANS): Britain on Monday condemned attacks on Saudi Arabian oil complexes as "despicable" and "outrageous", and called for "clear and united" international response to it.
British Foreign Secretary Dominic Raab told Sky News: "The attack on the Aramco installations was a wanton violation of international law. It's despicable."
"It's an outrageous act and we need to have as clear and united as possible international response to it."
Yemen's Houthi rebels on Saturday claimed responsibility for the drone attacks on two Aramco oil plants in the eastern part of Saudi Arabia.
Drivers in Britain were warned on Monday that a dramatic spike in the oil price could add around 2 pence (0.024 US dollars) to the cost of a litre of petrol in the coming weeks.
The Saturday strike affected some 5 per cent of the global oil supply, reports said.
