The United States resumed strikes on Iran Tuesday following a series of attacks from Tehran on commercial ships in the Strait of Hormuz.

US Central Command said they made strikes on more than 80 targets as 'punishment' for the three vessels attacked. Iran responded with strikes targeting Bahrain and Kuwait as the ceasefire continued to fall apart. 

'Forces completed a new round of offensive strikes against Iran, July 7, hitting over 80 targets with precision munitions as an immediate response to Iran's latest attacks on commercial vessels transiting the Strait of Hormuz,' CENTCOM said in a statement.

'US forces struck Iranian air defense systems, command and control networks, coastal radar sites, anti-ship missile capabilities, and more than 60 Islamic Revolutionary Guard Corps small boats in and near the strait.' 

CENTCOM said the strikes were in response to Iranian attacks on three ships that were transiting the Strait of Hormuz. 

'Iran's demonstrated aggression was unwarranted, dangerous, and a clear violation of the ceasefire,' they said.

One official told CNN that 'this is punishment' and that the strikes 'won't be over for a bit.'

Another said the military targeted Iranian air defense systems, coastal surveillance systems, ground-to-air missiles as well as launch sites for anti-ship cruise missiles and drones as part of the strikes. 

Iranian port facilities are also being targeted, the official added.

The US identified the ships struck as: Marshall Islands-flagged M/T Al Rekayyat, Saudi Arabia-flagged M/T Wedyan, and Liberian-flagged M/T Cyprus Prosperity.

Iran retaliated with strikes targeting Bahrain and Kuwait. Wednesday morning, both Bahrain, home to the US Navy´s 5th Fleet, and Kuwait, home to US Army forces, sounded missile alerts.

Iran´s paramilitary Revolutionary Guard issued a statement acknowledging targeting US military installations in both countries.

'The child-killing and terrorist US Army... openly violated the ceasefire and violated the Islamabad understanding by launching an airstrike on a number of coastal bases and civilian stations on the coasts of Hormozgan and Mahshahr provinces,' it said, without addressing the attacks on ships in the strait.

Bahrain sounded its alert a second time later Wednesday morning.

The Iranian foreign ministry has also accused the United States of violating the two countries' memorandum of understanding and said they have repeatedly violated parts of it.
