Saudi Arabia’s crown prince warned in an interview aired on Sunday that crude prices could spike to “unimaginably high numbers” if the world did not come together to deter Iran, but said he would prefer a political solution to a military one.

“If the world does not take a strong and firm action to deter Iran, we will see further escalations that will threaten world interests,” Crown Prince Mohammed bin Salman told the CBS programme ‘60 Minutes’.

The crown prince, in an interview conducted on Tuesday, said he agreed with US Secretary of State Mike Pompeo that the September 14 attacks on the kingdom’s oil facilities were an act of war by Iran.

But he said he preferred a peaceful resolution because that “is much better than the military one”. He added that a war between Saudi Arabia and Iran would collapse the global economy.The United States, European powers and Saudi Arabia have blamed the attacks on Iran. Tehran has denied any involvement.
