BBC:
Western technology and finance are helping Ukraine carry out hundreds of long-range strikes inside Russia.
That is despite Nato allies still refusing to give Ukraine permission to use Western-supplied munitions to do so – mostly because of fears of escalation.
Ukraine has been stepping up its long-range strikes inside Russia over the past few months, launching scores of drones simultaneously at strategic targets several times a week.
The targets include air force bases, oil and ammunition depots and command centres.
Ukrainian firms are now producing hundreds of armed one-way attack drones a month, at a fraction of the cost it takes to produce a similar drone in the West.
One company told the BBC it was already creating a disproportionate impact on Russia’s war economy at a relatively small expense.
