HUMAN rights campaigners marched on Downing Street yesterday in protest against Britain’s continued arms sales to Saudi Arabia that may have already been used to commit war crimes.

Activists from Amnesty International dressed in white boiler suits and carrying five giant dummy missiles drew attention to the government’s refusal to halt exports of British arms to the Saudi regime.

Since Yemen’s civil war erupted a year ago, thousands of civilians have been killed and injured, many in devastating air strikes conducted by a Saudi-led military coalition.
