THE US and Britain defended to the UN Security Council the legality of strikes they launched against Yemen's Houthis for attacking Red Sea shipping while Russia and China accused the Western allies of raising regional tensions.
Russia called the US and British operation disproportionate and illegal.
Other countries expressed concerns that the US and British strikes against 28 locations would stoke regional tensions, already high over Israel's offensive against Gaza's ruling Hamas Islamists.
The exchanges came during a Security Council debate on the US and British operation carried out after months of drone and missile attacks by the Iran-aligned Houthis on ships in the Red Sea and Gulf of Aden.
The Houthis, who seized much of Yemen in a civil war, say their attacks are in support of Hamas.
US Ambassador Linda Thomas-Greenfield said the strikes by the US and Britain, part of a US-led multinational naval coalition, were consistent with international law and the UN Charter.
The operation was designed "to disrupt and degrade the Houthis' ability to continue the reckless attacks against vessels and commercial shipping," she said.
The US, she continued, would continue pursuing a diplomatic response while seeking to defend commercial shipping.
More than 2,000 ships have been forced by the Houthi attacks to divert from the Red Sea since November.
"We took limited, necessary and proportionate action in self-defense alongside the United States with the non-operational support of the Netherlands, Canada, Bahrain and Australia," said British Ambassador Susan Woodward.
Russian Ambassador Vassily Nebenzia charged that the US and British strikes violated international law and raised regional tensions.
"It's one thing defending commercial shipping, attacks on which are unacceptable, but another when you're disproportionately and illegally bombing another state," he said.
Zhang Jun, China's UN envoy, said the Security Council had not authorised the use of force against Yemen.
The US and British operation "not only caused infrastructure destruction and civilian casualties, but have also resulted in heightened security risks in the Red Sea," he said.
