Police have arrested 45 anti-Trident protesters staging a blockade of the Faslane naval base.
The Scrap Trident Coalition is carrying out the blockade after around 2000 turned out for a march and rally in Glasgow's George Square on Saturday.
Faslane Naval Base, near Helensburgh in Argyll, is home to the UK's Trident weapons system, which campaigners want disarmed.
The large demonstration is taking place at the north and south gates of the base on Monday morning, and hundreds of people attended.
A spokeswoman for Police Scotland said 29 women and 16 men were arrested, amending an earlier total of 47, all for alleged offences relating to breach of the peace and resisting arrest.
It began at 7am with several members of the group, which includes the Green Party, the Scottish CND and the Stop the War Coalition, staging the action, which they hope will force the base to close for the day.
One of the organisers, Brian Larkin, from the Scrap Trident group and co-ordinator of the Edinburgh Peace and Justice Centre, said: "We want the resources that go into Trident to fund disability benefits, create jobs, scrap the bedroom tax, fund the NHS, fund education and fund welfare.
"Obviously you can't fund all of it with that but we want further cuts in the military. We don't want to be associated with Nato, we want Scotland to take a different tack from the UK and to be true to itself.
"This time around there's a strong feeling against the current Con-Dem Government's programme of austerity measures. The poorest people are paying the price; regular, ordinary working people."
He added: "The momentum is moving in the nuclear disarmament movement. Now is the time to make a concerted effort to disarm Trident and not replace it with any other nuclear weapons system."
"One hundred and eighty-seven countries in the world don't have nuclear weapons. What do we need them for?"
Organisers said students, pensioners, trade unionists and environmentalists all took part in the protest. Nicole MacLean, a student from Falkirk, said: "We want to set a precedent for other countries.
"I know it's hard with nuclear to give it up but if we've got people behind supporting it, saying this is what we want, I think it sends a positive message to the world to get rid of nuclear weapons."
Leonna O'Neill, 27, who has lived in the Faslane peace camp for two-and-a-half years, said: "By building up to this we show people they can actually affect the situation and put their bodies in the way of these weapons. We don't have to be complicit.
"I think Parliament needs a bit of a push and certainly there needs to be a much bigger mass movement of people. And it's been a long time since there was a blockade like this at Faslane, so we're starting again from scratch."
Green MSP Patrick Harvie attended the protest. He said: "If Scotland decides next year to take control of its own defence and foreign affairs policy, we will be able at last to consign Trident to history and make Scotland a force for peace in the world.
"David Cameron has been quite shameless in milking the situation on the Korean peninsula in terms of the Trident debate.
"Most people clearly know that North Korea does not pose a direct threat to the UK at present and even if it did, Trident as a response to that is a weapon which is only capable of the mass slaughter of innocent people.
"It is not something that would be morally defensible to use."
The Fund Human Needs blockade is one of more than 100 similar protests in dozens of countries as part of a Global Day of Action on Military Spending.

Am vergangenen Montag haben sich 250 Menschen an der Militärbasis Faslane-on-Clyde in Schottland versammelt, um dafür zu protestieren, dass die britischen Nuklearwaffen verschrottet werden. Einige der Demonstranten haben sich an die Tore der Militärbasis angekettet und wurden von schottischen Polizisten freigeschnitten. Etwa 47 Menschen sind bei den Protesten festgenommen worden, darunter Chas Booth, Mitglied der schottischen Grünen mit Sitz im Stadtrat von Edinburgh.

Organisiert wurden die Proteste von der „Scrap Trident Coalition“, die die britische Regierung dazu bringen will, das Waffensystem „Trident“ auszurangieren. Nach Angaben der Trident-Gegner würden in den nächsten 50 Jahren 100 Millarden britische Pfund für diese Waffen ausgegeben. Diese Summe solle stattdessen für andere Zwecke ausgegeben werden, die eher menschlichen Bedürfnissen entsprächen, zum Beispiel Sozialhilfe, Rente, Invalidenrente und Arbeitsplätze im Bereich der erneuerbaren Energien. Dem Protestbündnis hatten sich verschiedene Gruppen und Einzelpersonen angeschlossen: Die Scottish Green Party, der Vorsitzende der britischen „Kampagne für nukleare Abrüstung“ Dave Webb, und Aktivisten der „Stop the War Coalition“.

Vorausgegangen war den Protesten eine Kundgebung mit 2000 Teilnehmern auf dem George Square in Glasgow am vergangenen Samstag. „Scrap Trident“ hat insgesamt drei Protesttage in Schottland geplant und sieht diese als Teil von mehr als 100 anderen weltweiten Protestaktionen im Rahmen des „Global Day of Action on Military Spending“ (Aktionstag gegen Rüstungsausgaben). 

In Faslane liegt die Militärbasis „Faslane-on-Clyde“, der Stützpunkt einer Flotte von Atom-U-Booten, die mit atomaren Raketen bestückt sind. Die britische Regierung wird voraussichtlich im Jahr 2016 darüber entscheiden, ob dieses Atomraketenprogramm erneuert wird.
