Sanaa (AP) - The Houthi rebels in Yemen have claimed to have attacked an oil field in neighboring Saudi Arabia with drones. In the attack on the Schaiba oil field in the east of the country ten drones were used, said a military spokesman for the Houthis. The attack was, among other things, a refinery. The state-owned Saudi oil company Saudi Aramco confirmed that there had been a fire at liquefied natural gas plants in Schaiba. There were no injuries. The oil production of the company was not affected, it said.
