An explosion occurred at Ukraine’s embassy in Madrid, injuring one employee who was handling a letter, the Spanish Interior Ministry said Wednesday.

The individual was slightly injured and is being treated at hospital, while police are investigating, the ministry said. …

“Whoever is behind this explosion they will not succeed in intimidating Ukrainian diplomats or stopping their daily work to strengthen Ukraine and to counter Russian aggression,” Nikolenko quoted Kuleba as saying.
