The Russian consulate in Gdansk will be closed, Sikorski announced at a press conference on Wednesday morning.
The Polish Foreign Minister points out that he has previously warned Russia of strong measures if hostile actions against Poland do not cease. Instead, Russia has escalated them, says Sikorski, according to Polish media.
The announcement about the consulate is only the first part of Poland's response to the weekend's events, the minister adds.
Blown up at night
On Sunday morning, blast damage was discovered on a train track between Warsaw and Lublin in eastern Poland, on a route where weapons and support have been transported further east to Ukraine.
A driver on a regional train discovered damage to the rails near a viaduct and the explosion is believed to have occurred earlier on Sunday night. No one was injured.
Later, additional damage was discovered at other locations along the same train track.
The intention appears to have been to blow up a train, Prime Minister Donald Tusk said early on, when Poland determined that it was a case of sabotage.
Two Ukrainians
Polish authorities say they have identified two people who allegedly carried out the sabotage in collaboration with Russian intelligence services. The two are said to be Ukrainian citizens who have collaborated with Russia for a long time. They are said to have traveled on to Belarus.
Russia continues to maintain an embassy in Warsaw. In recent years, in addition to its war of invasion in Ukraine, the country has been accused of widespread sabotage and various forms of hostile intervention in European countries. According to authorities and experts, this is aimed at undermining support for Ukraine's defense, causing unrest and sowing division.
Kremlin spokesman Dmitry Peskov said in a comment on Poland's decision that the countries' relationship seems to be breaking down completely and that they "can only regret it". The Foreign Ministry in Moscow then announced that retaliatory measures would be taken in Russia.
