A demonstration is taking place outside an arms factory in Brighton by pro-Palestinian protesters.
Gates at the L3 Harris factory in Home Farm Business Park have been blockaded by activists waving flags and holding banners.
The Workers for a Free Palestine group is targeting four factories in the UK which it says supply components for arms used by Israeli forces.
L3 Harris has been contacted by the BBC for comment.
Instro Precision, a subsidiary of the Israeli defence company Elbit Systems, in Broadstairs, Kent, has been the target of previous protests.
Protests are taking place at Eaton Mission Systems in Bournemouth, BAE Systems at Samlesbury Aerodome in Lancashire and BAE Systems at Govern in Glasgow.
