In the northern Danish city of Aalborg, the firm MyDefence makes equipment that jams and repels drones.

"We've had a big surge of interest," says chief executive, Dan Hermansen.

He says that up until early October his company was mainly dealing with defence firms, but now it has "completely shifted".

The small, box-like kit made by MyDefence is mostly used by the military of Nato countries and Ukraine.

However lately demand has grown from civilian customers.
