Vigils have been held across Scotland to mark the 60th anniversary of the Hiroshima atomic bomb.
The attack and its aftermath killed an estimated 140,000 people at the end of World War II.
Events commemorating the bombing took place in Glasgow, Edinburgh, Dundee, Stirling and Dumfries.
The Campaign for Nuclear Disarmament (CND) said Scots should remember the victims of war and why such weapons should be scrapped.
Campaigns worker Phill Jones said: "The commemorations highlight how nuclear weapons are so different from any other weapons - a fact quite often forgotten in this day and age.
"The Trident submarines at Faslane, only 30 miles from Glasgow, have carried nuclear bombs that are seven or eight times more powerful than the bomb that was dropped on Hiroshima.
"One of the reasons why this year is significant, as well as being the 60th anniversary, is that in the next few years the government will have to decide whether to replace Trident or not."
Glasgow City Council leader Steven Purcell and Deputy Lord Provost Christine Devine attended a vigil in the city's George Square, along with CND, unions and other campaigners.
In Edinburgh the launch of the Festival of Spirituality and Peace marked the 60th anniversary of Hiroshima at St John's Church on Princes Street.
Dundee's 25th annual peace walk up The Law was followed by a rally, which included anti-war campaigners Rose Gentle, Aamer Anwar, and politicians Rosie Kane and Stuart Hosie.
One of the biggest peace events in Britain was in London where a ceremony was held in Tavistock Square, close to where a bomb exploded on a double decker bus on 7 July.
In Hiroshima about 55,000 people thronged into the city's peace park early on Saturday morning to remember the moment the bomb exploded in the skies above the city 60 years ago.
At 0815 on 6 August, 1945 the Enola Gay dropped the bomb that exploded over Hiroshima, obliterating the centre of the city and killing at least 140,000 people.
Three days later, Bock's Car dropped a bomb on Nagasaki, killing another 80,000.

3. The aircraft then performs a sharp, 155 degree right turn and dives an estimated 518 metres
4. The bomb explodes with a force of 13 kilotons at a height of approximately 576 metres above the city
5. About a minute later the first shock wave, travelling at about 335 metres per second, hits the aircraft
