ANTI-ARMS trade activists protested outside weapons manufacturer Lockheed Martin’s London HQ last night against its profiteering from “human catastrophe” in Yemen.

The arms giant produces many of the weapons and war machines sold by Britain and the US to Saudi Arabia, which is waging a brutal war on Yemen.

Campaign Against Arms Trade (CAAT) warned that the Saudi-led bombing campaign — which began in March 2015 — had created a “human catastrophe” and Lockheed Martin had “profited every step of the way.”

The government has granted export licences for weapons worth a staggering £3.3 billion since the start of the conflict.

And the arms trade is so lucrative for Lockheed Martin that it has set up a subsidiary company in Saudi Arabia to increase profiteering from the sale of arms, including Hellfire missiles and F-16 fighter jets.

According to Amnesty International three million people have fled their homes with almost 19 million people — 70 per cent of the population — requiring urgent humanitarian aid and assistance as a result of the war.

A UN report released earlier this year showed that at least 10,000 people have been killed by indiscriminate bombing.

London CAAT spokesman Ian Pocock said: “As the world’s largest arms company, Lockheed Martin is responsible for untold harm and profits from conflict around the world.

“The bombing of Yemen has created a humanitarian catastrophe and Lockheed has profited every step of the way.”

CAAT has lodged a judicial review to halt arms sales to Saudi Arabia with the verdict expected later this month.
