Bulgarian Prime Minister Boiko Borisov says coalition airstrikes against Libya lack clear goals and ways to achieve them.
Borisov told the private channel TV7 on Monday that he can't send Bulgarian pilots to take part in such an "adventure."
He suggested that Libya's future oil exploitation was behind the operation spearheaded by France, Britain and also backed by the United States.
Borisov said hundreds of thousands have been killed in other African countries but no international military operations have been conducted there.
Borisov said that financial and economic pressure on the regime would have been more efficient and voiced hope that NATO would take over command so that "at least we know who is in charge."
