Iran and Israel traded strikes on key energy facilities in the Middle East, complicating U.S. efforts to curb turmoil in markets as the conflict stretched toward three weeks.?

Qatar¡¯s Ras Laffan Industrial City ¡ª the complex that houses the world¡¯s largest liquefied natural gas export plant ¡ª suffered ¡°extensive damage¡± after an Iranian attack, state-owned QatarEnergy said, without providing more details.

The strike followed a warning from Tehran hours earlier that a number of energy sites in Gulf countries would be considered ¡°legitimate targets¡± after Israel attacked a key gas field in Iran. Facilities in Qatar, Saudi Arabia and the United Arab Emirates were on a list of sites at risk of Iranian airstrikes, the semi-official Tasnim news agency reported on Wednesday.?
