Ukrainian drone attack causes large explosion at arsenal in Toropets, more than 300 miles north of Ukraine

A Ukrainian drone attack on a large Russian weapons depot caused a blast that was picked up by earthquake monitoring stations, in one of the biggest strikes on Moscow's military arsenal since the war began.

Pro-Russian military bloggers said Ukraine struck an arsenal for the storage of missiles, ammunition and explosives in Toropets, a historic town more than 300 miles north of Ukraine and about 230 miles west of Moscow.
