In Europe, the main stock markets opened mixed on Tuesday morning, with the price of Brent Crude rising following the US strikes on Iran, which have raised doubts whether the two sides will be able to reach a peace agreement any time soon.

US Secretary of State Marco Rubio said on Tuesday that the Strait of Hormuz must remain open “one way or another” and that negotiations with Iran are continuing, but that resolving the discrepancies in the initial draft will take “a few days”.
Rubio’s comments came hours after the US forces attacked military targets in southern Iran, in an operation described by Washington as an act of “self-defence” to protect its troops from threats by Iranian forces.
US Central Command justified the attacks as a measure of self-defence, assuring that restraint would be maintained during the current ceasefire, and that the operation targeted missile launch sites and vessels attempting to lay mines.
Investors will once again look to Wall Street for guidance on Tuesday, in a session highlighted by the publication of the Conference Board's May US consumer confidence index.
