On 1 July, three activists from Manchester Palestine Action began a three-day rooftop occupation of a Israeli-owned arms factory, the five-storey-high Elbit Ferranti building in Oldham.
The same day, activists entered Elbit-owned Instro Precision, in Sandwich, Kent, blockading both gates.
The protests marked the fifth anniversary of Israel's 'Protective Edge' assault on Gaza which killed around 1,500 Palestinian civilians.
Elbit supplies four out of five drones used by the Israeli military, one part of its £500m sales to the Israeli ministry of defence.
All activists were released without charge.
