Myanmar's Kachin State, among them women, children and the elderly, local media reports and sources in the area said on Tuesday.
Reuters could not immediately verify the reports. The Kachin media and local sources said the incident took place close to midnight on Monday, a few kilometres from a military camp run by the Kachin Independence Army (KIA), which is in conflict with Myanmar's ruling military.
The KIA could not immediately be reached for confirmation. The reports were shared on social media by a local activist and a minister in Myanmar's shadow National Unity Government, who did not immediately respond to request for confirmation.
