Trump says renewed bombing of Iran possible after midterms polls

US President Donald Trump says it is "possible" the US could increase its bombing campaign against Iran after the midterm elections.

Meanwhile, the US-led Joint Maritime Information Center raised the security threat level for the Middle East Maritime Region to "severe" following a series of attacks on oil tankers in the Strait of Hormuz.

In an interview with Time Magazine, US President Donald Trump said it was "possible" the US could increase its bombing campaign against Iran after the midterm elections.

Trump also said he had rejected Iran's proposal to reopen the Strait of Hormuz.

Trump said if a deal with Iran cannot be reached, a military strike might be launched, and the time for making a decision is drawing near.

The US President also said he doesn't believe the Iran War will have any impact on his success in the US midterm elections.

TRUMP: "Well, it's possible. I don't - it should help. Because Iran will not have a nuclear weapon. So when you say, is it okay for Iran to have a nuclear weapon, I would say 100 percent of the people say no, including worldwide. So when you say it that way, it would help. If you don't say that, it could hurt, yeah."

Meanwhile, the US-led Joint Maritime Information Center raised the security threat level for the Middle East Maritime Region to "severe" following a series of attacks on oil tankers in the Strait of Hormuz.

At least four maritime safety incidents involving oil tankers occurred in the Strait of Hormuz between September 28 to 29, the advisory said.

On Sept 28, an oil tanker leaving the Strait of Hormuz was struck by an unknown projectile, causing a small fire on board that was quickly extinguished.

On Sept 29, three oil tankers transiting the Strait of Hormuz were hit by unidentified projectiles.

The crews of two of the tankers were unharmed, and the vessels subsequently underwent damage assessments.

The status of the crew and the extent of damage to the third tanker are still under investigation.

Iran's Persian Gulf Strait Authority said on Thursday several oil tankers were struck in the Strait of Hormuz over the past days, of which the last three ones are owned or rented by the United Arab Emirates.
