The UK has been training dozens of Saudi Arabian military officers since the beginning of the kingdom’s military aggression against Yemen in March 2015, a new report suggests, further revealing the extent of Britain’s involvement in the deadly conflict.

Axar.az reports that, according to a report published by The Guardian on Wednesday, more than 40 Saudi cadets – including a dozen who came last year – have been training at the Royal Military Academy of Sandhurst, the Royal Air Force (RAF)’s school at Cranwell and the Royal Naval College since 2015.

The majority of the 43 cadets have been training at the Britannia Royal Naval College in Dartmouth.

The UK military confirmed the report after a freedom of information request by the British paper, which was initially rejected by the UK Ministry of Defense (MoD) but later overturned on appeal.

The ministry refused to say how much money London was going to pocket from the Saudi training, arguing that it could harm relations with the Saudis. It also argued that other companies or states competing with the UK to train Saudi cadets could benefit from such information.

Mohammed Ali al-Houthi, the Chairman of the Supreme Revolutionary Committee of Yemen, has condemned London's role in the war, saying it was not possible for the UK to be a peacebroker in the country and an arms seller at the same time.

Since the beginning of the war, the Saudi air and land forces have launched a campaign of airstrikes as well as a ground offensive against Yemen while the kingdom’s naval forces have maintained a blockade on Yemen.

The UN Committee on the Rights of the Child has warned that the Saudi blockade is exacerbating a a severe lack of food and medicine which has hit children the hardest.
