Conflict in the Middle East is affecting a key energy lifeline for Europe. How big is the risk?

Missiles and drones are flying in the Red Sea, disrupting one of the world's key trade arteries and a chokepoint for energy shipments headed for Europe. Attacks by Yemen's Houthi rebels over Israel's war with Hamas are posing a new threat to the future of energy supplies to the 27-country European Union, which relies on imported natural gas to power factories, generate electricity and heat homes. Tankers carrying liquefied natural gas — which is supercooled to travel by ship instead of pipeline — routinely pass through the Red Sea, and several shipments to Italy already have been canceled.
