The US and Israel launched strikes at Iran over the weekend, prompting concern and outrage from experts.

Prime Minister Christopher Luxon and Foreign Minister Winston Peters have criticised Iran's counter attacks, prompting Helen Clark to call the Government's response 'one-sided'.

Waikato University law professor Al Gillespie has said this attack was illegal by the standards of international law.

"There's nothing in the UN charter that says you can bomb someone who won't negotiate...the exemption to that was if this was a pre-emptive attack and it was an overwhelming necessity, and that cannot be seen in this instance."
