That was written by the Prime Minister on his official Facebook page

Bulgaria's Prime Minister Kiril Petkov annonunced a public campaign for raising money for buying ammunitions. He called on the Bulgarians to donate one of their monthly salaries. 

"Sending military aid to Ukraine requires political but also social unity. I think it is time to turn this public energy into real action," Petkov wrote on his Facebook page.

According to him, until a political consensus is reached on the topic of providing military assistance, every citizen could choose to help Ukraine financially.
