The foreign ministers of the Group of Seven nations have condemned what they described as "unacceptable continued strikes" by Yemen's Houthi movement against Saudi Arabia.

The ministers issued a joint statement on Monday following an informal meeting held on the sidelines of the United Nations General Assembly in New York.

"We condemn in the strongest terms the unacceptable continued strikes carried out by the Houthis in Yemen and against the Kingdom of Saudi Arabia," the ministers of the UK, Canada, France, Germany, Italy, Japan and the United States said.

The statement called on the Houthis "to immediately cease all military actions, all threats and attacks against civilian shipping, and to return to the political process in good faith."

The ministers also called on Iran to stop arming and supporting the group, saying Tehran is in violation of past UN Security Council resolutions. They added that Iran's backing of the Houthis constituted a dangerous pattern of escalation that risked undermining international trade and creating global instability.

The latest escalation follows a period of relative calm that had largely held since the UN-brokered ceasefire in 2022 between the Iran-aligned group and the Saudi-backed Yemeni government.

Separately, according to reports, Saudi Arabia is weighing Washington's refusal to help fend off Houthi attacks after Riyadh requested US assistance, despite the two countries being longstanding allies and President Donald Trump and his family maintaining close personal ties with Saudi leaders.
