Spanish police intercepted three more envelopes containing animal eyes addressed to Ukraine's embassy in Madrid and its consulates in Barcelona and Malaga on Monday, police sources close to the investigation said.
Last week, Ukraine said a series of "bloody packages" were sent to its missions across Europe, soon after a letter bomb detonated at Ukraine's embassy in Spain and police defused others sent to, among others, Prime Minister Pedro Sanchez.
The postal service's security staff detected the new envelopes during screening on Monday morning and alerted police, the sources said. Officers found no explosive or flammable substances inside, the sources added.
