One employee has been injured by a blast at the building of the Ukrainian Embassy in Madrid. Oleh Nykolenko, the embassy's representative, said on Facebook on November 30 that an envelope delivered by post exploded when it was being examined by the building's superintendent, who sustained non-life-threatening injuries. Ukrainian Foreign Minister Dmytro Kuleba has asked his Spanish counterpart to thoroughly investigate the situation and urged Ukrainian embassies abroad to boost security measures.
