Police today arrested five anti-war protesters outside the Northern Ireland offices of US defence firm Raytheon.
Nine women chained themselves together on the top floor of the building at the science and technology park in Londonderry in protest at the Israeli offensive in Gaza.
The demonstration by the Derry Anti-War Coalition began at the Springtown plant at about 2.30pm today.
The women were later allowed to leave by police and the protest has ended.
Those arrested were men aged between 18 and 66.
The five men were later charged with a range of offences including criminal damage, obstructing, resisting and assaulting police and burglary.
They will appear next month at Londonderry Magistrates' Court.
