Americans have taken to social media to condemn the US government for supplying the Saudis with bombs used to kill innocent children in Yemen.

CNN on Friday confirmed that a bomb used by the Saudi-led coalition last week in an attack on a school bus in Yemen, which killed dozens of children, had been supplied by the US.

People from around the world concerned with the criminal activities going on in Yemen posted condemnations on social media on Saturday.

US actor Jim Carrey tweeted that Saudi Arabia is a US ally and that makes Washington an accomplice in the killing of 40 innocent children.

Weapons experts told CNN on Friday that the bomb was a 227-kilogram laser-guided Mark 82 bomb.

They also noted that the numbers on the weapon identified major US military contractor Lockheed Martin as its maker.

Political consultant Peter Daou asked why the US was supplying bombs to slaughter children in Yemen.

Ed Krassenstein of the Washington, DC-based political newspaper and website The Hill wrote that former US President Barack “Obama banned the sale of these bombs to the Saudis but Trump lifted that ban as part of his attempt to undo everything Obama did.”

The Saudi attack on a school bus in the town of Dhahyan on August 9 that killed a total of 51 people, among them 40 children, and left 79 others wounded, sparked outrage from international human rights groups and UN officials.

UN Secretary General António Guterres condemned the attack and called for an “independent and prompt” probe into the air strike.

Guterres emphasized that “civilians and civilian objects” be spared from attacks.

The bus targeted by the Saudi forces was carrying a group of young school children attending summer class.

Some 15,000 Yemenis have been killed and thousands more injured since the onset of the Saudi-led aggression on Yemen in March 2015.

The United Nations says a record 22.2 million Yemenis are in need of food aid, including 8.4 million threatened by severe hunger.
