Police seen outside Ukraine's Madrid embassy

STORY: The letter, which arrived by ordinary mail and was not scanned, caused "a very small wound on the ring finger of the right hand" of the employee after he opened it in the garden of the embassy, Spanish government official Mercedes Gonzalez told broadcaster Telemadrid. He went to hospital under his own steam for treatment.

It was addressed to Ambassador Serhii Pohoreltsev, she said. In the wake of the incident, Ukrainian Foreign Minister Dmytro Kuleba ordered all Kyiv's embassies abroad to "urgently" strengthen security, a ministry spokesperson said.

Kuleba said the perpetrators "will not succeed in intimidating Ukrainian diplomats or stopping their daily work on strengthening Ukraine and countering Russian aggression."

Detectives were probing the incident, aided by forensic and intelligence investigators, Spanish police said. Spain's High Court will lead the investigation.
