(ANSA-AFP) - BELGRADE, MAR 31 - Several European diplomats were in Kyiv on Tuesday to mark the four-year anniversary of the Bucha massacre and reaffirm their support for Ukraine, amid ructions in the bloc over Hungary blocking a 90-billion-euro loan for the country. The European Union's top diplomat Kaja Kallas, as well as the foreign ministers of Germany, Poland, Italy and other EU countries were in Ukraine for the occasion. "Each visit is a powerful reminder of Ukraine's courage and resilience. Europe stands by your side. We will keep providing military, financial, energy, and humanitarian support," Kallas said on X. The diplomats later visited the Kyiv suburb of Bucha, where they marked the four-year anniversary of a Russian massacre there. (ANSA-AFP).
