Denmark faces increased Russian naval provocations in its straits, risking escalation. Despite no direct threat, tensions remain high as Denmark supports Ukraine.
COPENHAGEN (Reuters) -Russian warships have repeatedly sailed on collision courses, aimed weapons at Danish naval vessels and disrupted navigation systems in Denmark's straits that connect the Baltic Sea to the North Sea, its defence intelligence service said on Friday.
Such incidents risk unintended escalation, it said.
The Baltic region remains on high alert after incidents involving undersea cables, gas pipeline outages, airspace violations and drone sightings since Russia's 2022 invasion of Ukraine, which increased tensions between Moscow and the West.
Denmark, a staunch supporter of Ukraine in its war with Russia, has beefed up its military budget and committed to acquiring long-range precision weapons capable of striking targets inside Russia.
RUSSIAN WARSHIPS POINT WEAPONRY AT DANISH HELICOPTERS, DANISH INTELLIGENCE SAYS
"We have seen several incidents in the Danish straits, where Danish air force helicopters and naval vessels have been targeted by tracking radars and physically pointed at with weapons from Russian warships," Danish Defence Intelligence Service Director Thomas Ahrenkiel told a press conference.
He said Russian warships had sailed on collision courses with Danish vessels during their passage through the straits.
Ahrenkiel said a Russian warship has been anchored in Danish waters for over a week, suggesting possible interference from Moscow if Denmark tried to curb movements of Russia's "shadow fleet" of tankers used to circumvent Western sanctions on its oil exports imposed over its war with Ukraine.
In May, tensions escalated in the Baltic Sea when Russia deployed a fighter jet during Estonia's interception of a Russian-bound oil tanker suspected of being part of the shadow fleet.
The Danish straits, a busy international shipping route, see frequent movement of Russian military vessels that are typically escorted by Denmark's navy.
Defence intelligence has also recorded Russian warships sailing through Danish straits with sonar and jamming equipment, according to Ahrenkiel. He said it was "highly probable" that they, on at least one occasion, had jammed signals and caused extensive GPS interference in Denmark.
Denmark's intelligence service assesses that Russia is conducting hybrid warfare against Denmark and the broader West.
"Russia is using military means, including in an aggressive way, to put pressure on us without crossing the line into armed conflict in a traditional sense," Ahrenkiel said.
Moscow has repeatedly denied responsibility for hybrid attacks in Europe. President Vladimir Putin joked on Thursday that he would not fly drones over Denmark anymore and described as "nonsense" the idea that his country would potentially target a NATO member.
NO DIRECT MILITARY THREAT DESPITE INCIDENTS
Despite the incidents, defence intelligence emphasised that there was no direct military threat against Denmark.
However, Prime Minister Mette Frederiksen last week described recent drone incursions over Danish airports and military installations as a "hybrid attack" on the country.
Defence Minister Troels Lund Poulsen said investigations into the incidents were continuing, with no conclusions yet on the identity of the perpetrator.
Hybrid threats, which include sabotage, disinformation, espionage and cyberattacks, have been flagged as increasingly aggressive by Western security agencies.
NATO has strengthened its Baltic operations in response to the drone incursions. Sweden proposed new legislation on Friday to expand maritime surveillance by its coast guard.

Hybrid warfare refers to a strategy that blends conventional military tactics with irregular tactics, such as cyber attacks and disinformation, to achieve strategic objectives without direct armed conflict.
Military escalation is the process by which a conflict intensifies, often involving increased military presence or actions that can lead to a larger confrontation.
Military intelligence is the collection and analysis of information about foreign militaries and potential threats, used to inform strategic decisions and operations.
A naval vessel is a ship or boat that is part of a navy, used for military purposes including combat, transport, and surveillance.
