Iran's latest attacks on neighbouring Gulf States come as US President Donald Trump sends contradictory signals about how long the war could last, fueling uncertainty that's causing markets to swing.

Iranian fired drones towards Saudi Arabia and Kuwait early Tuesday as the war in the Middle East shows no sign of abating.

The Saudi Defense Ministry said it has destroyed two drones over the kingdom's oil-rich eastern region, while in Kuwait, the National Guard said it shot down six drones attacking the county's northern and southern areas.

Iran's latest attacks on neighbouring Gulf States come as US President Donald Trump sends contradictory signals about how long the war could last, fueling uncertainty that's causing markets to swing.

The president on Monday told Republican lawmakers that the war was likely to be a "short excursion," but hours later posted on social media that "If Iran does anything that stops the flow of Oil within the Strait of Hormuz, they will be hit by the United States of America TWENTY TIMES HARDER than they have been hit thus far."

In an apparent response to Trump's remarks published in Iranian state media, a spokesperson for the paramilitary Revolutionary Guard, Ali Mohammad Naini, said "Iran will determine when the war ends."

Kamal Kharazi, foreign policy adviser to the office of the supreme leader, told CNN on Monday that Iran is prepared for a long war. He said he sees no "room for diplomacy anymore" unless economic pressure prompts other countries to intervene and stop the "aggression of Americans and Israelis against Iran."
