LONDON, Sept 8 (Reuters) - The yen surged on Tuesday and stocks fell after a volley of attacks on energy facilities around the Gulf drove oil to near $100 a barrel, while copper prices hit record highs.

Brent crude futures hit their highest in six weeks, nearing $99 a barrel, after Yemen's Iranian-backed Houthis attacked energy facilities and cities in Saudi Arabia, highlighting the risk of the conflict spreading throughout the region and further complicating the supply of fuel to world markets.

The price of diesel has hit record highs and has almost doubled from where it was before the start of the conflict, as has gasoline, and even prices for physical crude for immediate delivery are well above futures prices, in a clear indication of the toll the conflict is taking on the global energy market.

Sept 8 (Reuters) - Operations at some energy facilities in Saudi Arabia, the world's top oil exporter, were halted on Tuesday following attacks by Yemen's Iran-aligned Houthis that wounded 73 people, in what Saudi authorities described as a dangerous escalation.
