Bulgaria refused to supply Ukraine with weapons from its military stockpiles.
Bulgaria no longer intends to transfer weapons from its reserves to Ukraine, Prime Minister Roman Radev said.
"We will no longer supply weapons and ammunition from the reserves of the Bulgarian army," BTA quotes him as saying.
Radev noted that under the current conditions, Sofia cannot allocate money to Kyiv due to problems with reserves, but will not prevent EU members from helping Ukraine.
A day earlier, Polish Prime Minister Donald Tusk said that Warsaw would no longer finance the purchase of American weapons for Kyiv.
Moscow has repeatedly warned that supplying weapons does not change anything and only prolongs the conflict. Lavrov stressed that such a charge would become a legitimate target.
