Warsaw police have arrested a man suspected of stabbing two Ukrainians on a bus over their nationality, police said. A court ordered him held in custody, and the charges he faces carry long prison terms.

Russia's full-scale war drove nearly a million Ukrainians to seek protection in Poland, and attacks on them for their nationality grew this year. Polish police received 180 reports of hate crimes against Ukrainians in the first half of 2026, over 30% more than a year earlier.

Police tracked the suspect to a forest

The attack took place on a Warsaw city bus in mid-October. The attacker stabbed and slashed two passengers, both Ukrainian citizens, and fled before police arrived. Both victims went to hospital with multiple stab and cut wounds. Police found that he attacked them because of their nationality.

Officers quickly identified the suspect but spent days locating him. The 30-year-old was hiding and living in a forest in Warsaw's northern Bielany district, where police detained him last weekend.

He faces three charges. Two concern the bus attack: attempting to cause grievous bodily harm, and causing injuries lasting more than seven days. The third covers threats against another man at a Warsaw venue in August 2024.

Police said he acted as a repeat offender, within five years of serving a prison term for a similar crime. The charges carry three to 20 years in prison. At prosecutors' request, a court ordered him held for three months.

This year's attacks on Ukrainians in Poland

In early August, Ukraine's ambassador to Poland, Vasyl Bodnar, said anti-Ukrainian remarks and attacks had risen by about 30%. Days later, people rallied in 22 Polish cities against violence toward Ukrainians and other minorities.

Other recent cases this year include:

• In late July, police in Wrocław detained two of three men suspected of beating a young Ukrainian couple.
• On 14 August, a woman allegedly attacked a Ukrainian girl and her younger brother in a Bydgoszcz park after hearing them speak Ukrainian. Prosecutors charged her four days later.
• In September, a man punched a 20-year-old Ukrainian tourist in the head at a crossing in central Warsaw, knocking him unconscious. Police detained the attacker, who gave no motive.

Tensions rose again in late September, when a Ukrainian man allegedly killed a priest in a knife attack at a monastery in Jarosław. Bodnar said some Polish politicians and journalists used it to argue for deporting Ukrainians.

Meanwhile, police in southwestern Poland detained a Russian citizen suspected of spying, after catching him photographing trains and railway infrastructure. Russia's suspected sabotage campaign keeps reaching Poland and the rest of Europe, and Ukraine's intelligence warned last week that Russia may stage sabotage in Eastern Europe and try to pin it on Kyiv.

Ukraine's security service (SBU) is teaching teenagers how to avoid recruitment by Russian intelligence online, the New York Times (NYT) reported on June 21.

"Maybe not all of these special operations are reported in the media — but believe me, the enemy is not sleeping... They are working actively and carrying out illegal activities, as strange as it may sound, directly inside your phones," SBU spokesperson Roksolana Yavorska-Isaienko told students.

Approximately 22% of Ukrainians recruited by Russian intelligence to conduct sabotage or terrorist attacks are minors, Artem Dekhtiarenko, SBU spokesperson, said on April 2.

Russian intelligence attempts to recruit Ukrainian civilians online, offering easy money in return for sharing sensitive data or preparing sabotage or terrorist acts.

Russian intelligence finds its recruits using social platforms, including Telegram, Discord, and TikTok.

Unsuspecting teenagers are often offered hundreds or even thousands of dollars to conduct simpler tasks such as delivering packages or taking photos of energy sites, the NYT reports.

More serious tasks are commonly assigned to teenagers once they have been blackmailed for conducting less serious operations beforehand or when their phones are hacked to reveal compromising photos.

Russian intelligence is actively attempting to recruit Ukrainian nationals for illegal operations across the EU, Ukraine's military intelligence agency (HUR) said on June 2.

"The recruitment of Ukrainians for hostile operations in Europe is yet another tool of hybrid aggression that the Russian Federation is waging against Ukraine and the entire European community," HUR said.

The SBU caught a Russian agent as he was filming a military airfield in preparation for a Russian strike, the agency reported on June 15.

The Russian Federal Security Service (FSB) recruited the unemployed 24-year-old via the Telegram messaging app to collect coordinates for air attacks on airfields and logistic depots, the SBU said.

The Russian FSB allegedly offered "easy money" and instructed the recruit to find military facilities and carry out reconnaissance on the ground.

Argentina has uncovered a Russian intelligence operation working to spread pro-Kremlin disinformation and influence public opinion, Argentine presidential spokesperson Manuel Adorni announced on June 18, citing the country's intelligence, according to AFP and Infobae.

The La Compania network, which is allegedly linked to the Russian government and the Kremlin's Project Lakhta, was led by Russian nationals Lev Konstantinovich Andriashvili and his wife Irina Yakovenko, who are both residents of Argentina, according to authorities.

The U.S. Treasury Department has previously accused the Project Lakhta, reportedly formerly overseen by late Russian oligarch Yevgeny Prigozhin, of election interference in the United States and Europe.

Prigozhin led the Russian Wagner mercenary group that was deployed in some of the deadliest battles in Ukraine, like the siege of Bakhmut. The oligarch was killed in a plane crash under suspicious circumstances in August 2023, around two months after leading a brief armed rebellion against the Kremlin.

Andriashvili and Yakovenko are accused of receiving financial support to recruit local collaborators and run influence operations aimed at advancing Moscow's geopolitical interests.

Their objective was to "form a group loyal to Russian interests" to develop disinformation campaigns targeting the Argentine state, Adorni said at a press briefing.

The spokesperson added that the alleged operation included producing social media content, influencing NGOs and civil society groups, organizing focus groups with Argentine citizens, and gathering political intelligence.

"Argentina will not be subjected to the influence of any foreign power," Adorni said, noting that while some findings have been declassified, much of the investigation remains a state secret.

Since Russia's full-scale invasion of Ukraine in February 2022, there has been a significant uptick in Russian migration to Argentina, some of which officials fear could be linked to covert intelligence operations.

Authorities reportedly said these espionage activities are often facilitated by a 2009 bilateral agreement between Argentina and Russia allowing visa-free travel, a deal that remains in effect despite growing security concerns.

In response to the threat, Adorni announced the creation of a new Federal Investigations Department (DFI) within Argentina's Federal Police, modeled in part on the U.S. FBI. The agency will focus on countering organized crime, terrorism, and foreign espionage, with investigators trained in advanced techniques and bolstered by experts in law, psychology, and computer science.
