Monday’s attack on the vital Houthi-controlled port of Hodeida was condemned by the United Nations as “one of the deadliest attacks on children” in the entire civil war, which has just entered its fourth year.
“We take this report very seriously and it will be fully investigated as all reports of this nature are - using an internationally approved, independent process,” a spokesperson for the Saudi-led coalition supporting Yemen’s exiled government said.
Rebel factions retaliated with an attack on a Saudi oil tanker in the Red Sea on Tuesday, causing “minor damage” to the ship, the Saudi coalition said. The attack occurred in international waters.
White House press secretary Sarah Huckabee Sanders said in a statement Wednesday that the US is “very concerned about the Houthis' latest attempt to escalate the war in Yemen.”
“We call on the Houthis to cease further escalation and demonstrate their commitment to a peace process by engaging in constructive dialogue,” she added.
Yemen slipped into full-blown civil war in March 2015 after neighbouring Riyadh led a coalition of Arab states in a bombing campaign designed to oust Iran-backed Shia Houthi rebels from the capital of Sanaa.
It has since descended into the worst humanitarian crisis in the world, with two thirds of the 28-million-strong population dependent on aid, eight million living on the brink of famine and the worst outbreak of cholera in modern history.
The disaster has to a large degree been caused by Saudi blockades of Houthi controlled ports and airspace, strangling imports of food and medicine.
International donors promised more than $2bn (£1.4bn) in humanitarian aid for Yemen at a pledging conference in Geneva on Tuesday.
The amount, however, fell well short of the appeal for $2.96bn (£2.1bn) in emergency funding to stop the country collapsing completely in 2018.
Western governments, including the UK and US, have been heavily criticised for selling weapons export licences to Saudi Arabia, which rights groups say are destined for use in Yemen’s war
