Hundreds of protesters blockaded the Faslane naval base in Scotland on Monday of this week.
The event was called by the Scrap Trident coalition.
It followed one of Scotland’s biggest marches against nuclear weapons on 4 April in Glasgow.
Faslane is where Trident nuclear submarines are based.
From early morning the protesters chained themselves to each other ahead of shift change. Some 34 people were arrested.
Scrap Trident said workers had been sent home after being held in their buses for hours in the nearby town of Helensburgh.
The protest was against the renewal of the Trident nuclear weapons system, which will cost over £100 billion, when it goes to a vote in parliament next year.
A protest was also held outside the Ministry of Defence in London later in the evening with the central message to “Vote out Trident”.
