Police have arrested 11 German anti-nuclear protesters outside the Faslane naval base.
The arrests were made outside the Faslane base
The group blockaded the main route to the Clyde base, which is home to the UK's nuclear submarine fleet, at about 0700 BST.
Strathclyde Police said nine women and two men were arrested, with more expected later.
On Monday, 25 protesters, including 11 French nationals, were arrested at Faslane.
They said they were demonstrating against the UK Government's plan to renew the Trident nuclear missile system.
The base has been the site of regular protests following the launch of the year-long Faslane 365 campaign in October last year.
