Minister of Foreign Affairs Dmytro Kuleba has stated that on the day when a parcel with a bomb was sent to the Embassy of Ukraine to Spain, two more diplomatic missions received letters with "very specific threats."

Kuleba said this on Thursday during the 29th OSCE Ministerial Council in Łódź, Poland, answering a question by Ukrinform.

"This is definitely a new form of terror. We are working very hard with the Spanish authorities to establish who is behind this. We certainly have a guess but we need to trace the entire network of agents and people involved in this campaign," said the Minister.

Kuleba added that on Wednesday "other alarming events took place, without explosives, but with very specific threats to embassies of Ukraine." He refused to name the diplomatic institutions.

As the Minister of Foreign Affairs claims, all these events let us say that there is a "targeted large-scale campaign" against Ukraine. "It is necessary to puzzle it out: who is involved, where it comes from, who sends them (letters)," Kuleba emphasised.

As previously reported, a third explosive hidden inside a parcel has been sent to the military airfield in Torrejón de Ardoz near the capital of Spain, Madrid.

In the afternoon of Wednesday, 30 November, it became known that an employee of Ukraine’s Embassy in Madrid was slightly injured after an explosion in the building of the diplomatic establishment. This incident was preliminary qualified as a terrorist crime in Spain.

After this, Dmytro Kuleba, Minister of Foreign Affairs of Ukraine, instructed to urgently strengthen the security of all Ukrainian embassies abroad and called on his Spanish counterpart to take immediate measures to investigate the attack on the Ukrainian diplomatic establishment.

The Spanish company Instalaza that produces weapons which the Spanish government sends to Ukraine in order to help fight the Russian forces also received a package, presumably with an explosive inside, on Wednesday, 30 November.
