Most Gulf bourses closed lower on Wednesday, ​after U.S. ⁠President Donald Trump said the memorandum of understanding to end ‌the conflict with Iran was "over", renewing fears of disruptions to Middle East oil ​supplies. The agreement, brokered by Pakistan last month to provide a 60-day window ​for negotiations, came ​under strain after the U.S. launched fresh strikes on Iran.

The U.S. said it had struck Iranian air defence ⁠systems, coastal surveillance facilities and drone launch sites, while Iran's Revolutionary Guards said they had targeted U.S. military positions in Bahrain and Kuwait, where air raid sirens sounded on Wednesday. Washington also moved to revoke ​a waiver ‌that had ⁠allowed Iran to sell ⁠oil on the global market, a move Iran's foreign ministry said violated ​the framework agreement aimed at ending the ‌war.

Brent crude futures were up $3.14, or ⁠4.23%, to $77.30 a barrel at 1231 GMT.
