Two Wildberries warehouses were hit by Ukrainian strikes overnight on Monday, with another site apparently linked to Russia's largest online retailer also damaged near Moscow. Ukraine has been targeting facilities operated by the company - often dubbed the "Russian Amazon" - in recent weeks. Elsewhere, officials did confirm two other Wildberries sites were hit in the St Petersburg and Tver regions. Kyiv says the depots supply the Russian military, which Moscow denies. Meanwhile, strikes launched by Russia across Ukraine killed at least four people.
