- Saudi, Kuwait refineries hit -

Drones struck a Saudi oil refinery on the Red Sea and caused fires at two others in Kuwait as Iran stepped up attacks on Gulf energy infrastructure.

Saudi Arabia's defence ministry said a drone crashed into the Samref refinery in the industrial zone of the Red Sea port of Yanbu, adding that damage assessment was underway.

Yanbu is the destination of Petroline, the overland oil pipeline that gives Saudi exports an alternative to the Strait of Hormuz -- currently choked off by Iran.

In Kuwait, drone attacks sparked blazes at the Mina Abdullah and Mina Al-Ahmadi refineries, which have a combined capacity of 800,000 barrels per day.

The state Kuwait National Petroleum Company later said the fires were contained.
