Tens of thousands of people danced and applauded in central Pyongyang, North Korea, in a show of support for the country's reported nuclear test earlier this week.
The country claimed via state TV that it had conducted a test of a miniaturised hydrogen nuclear device - known as a H-bomb - after the detection of a 5.1-magnitude earthquake near its known nuclear test site on Wednesday.
Organisers of the support rally, which lasted into the evening and included a fireworks display, said 100,000 people took part.
This type of mass rally happens several times a year in Pyongyang, when authorities decide they want to highlight particular policies or events.
They have also not addressed doubts over whether it really was a H-bomb explosion as claimed.
The nuclear test is the fourth by the isolated country, which is under US and UN sanctions for its nuclear and missile programmes and facing more for this further incursion.
The US Geological Survey said the 5.1-strength earthquake was bigger than the previous three caused by bombs North Korea tested in 2013, 2009 and 2006.
