Ukraine conflict: Spanish suspects held for 'joining rebels'
The Spanish interior ministry published images apparently showing the suspects in combat gearPolice have arrested eight Spaniards accused of fighting alongside pro-Russian rebels in eastern Ukraine.
The suspects were detained in raids in six regions across Spain, the interior ministry said, describing the operation as the first of its kind in Europe.
They face charges of complicity in murder, possession of weapons and violating Spain's neutrality in the conflict.
Rebels have been fighting government forces in eastern Ukraine since April.
The eight Spanish fighters were arrested after returning recently from Ukraine where they took part in the conflict in the Donbas region last year, the interior ministry said.
During their stay, the suspects posted pictures of themselves on social media with assault rifles and explosives.
"This is the first police operation conducted in Europe against the activities of foreign fighters in the Ukrainian conflict," the ministry said.
Spanish officials say the men joined separatists in Ukraine last yearMedia reports said the men had been inspired by the International Brigades, the multinational volunteer forces that fought against Francisco Franco's uprising during the Spanish Civil War. They had posted messages online about their commitment to fighting in Ukraine, vowing to fight fascism.
Spain's El Pais newspaper said the suspects belonged to different communist groups and had received support from an unofficial pro-Russia network in Europe.
Foreign fighters
- Tiny numbers of EU citizens have fought on both sides in Ukraine's bitter conflict, either as volunteers or mercenaries
- EU states with citizens involved include Spain, France, Germany, Italy, Poland and Sweden
- A handful of hardline Spanish leftists have openly sided with the rebels, saying they are repaying Soviet support during the Spanish Civil War
- The EU has resisted Ukrainian calls to designate the rebels as "terrorists" - a designation it applies to other militant groups such as Colombia's Farc
'White power' warrior from Sweden
Two Spanish leftists, Angel Davilla-Rivas and Rafa Munoz Perez, spoke to the media last year about fighting for the pro-Russian rebels. They said it was in recognition of the Soviet Union's support for the Republican side in the Spanish Civil War.
Spain's interior ministry has not named the suspects arrested on Friday.
Police say the detainees posted pictures of themselves online with weapons in Ukraine
The operation in Spain is said to be the first against foreign fighters in Ukraine.Forces on both sides of the conflict in Ukraine are said to have attracted foreign fighters. Swedish neo-Nazis were last year reported to have been fighting with the Azov Battalion, a pro-government volunteer armed group.
The Ukrainian government, Western leaders and Nato say there is clear evidence that Russia is helping the rebels with heavy weapons and soldiers.
Independent experts echo that accusation while Moscow denies it, insisting that any Russians serving with the rebels are "volunteers".
Fighting began in Ukraine's eastern Donetsk and Luhansk regions - known as Donbas - last April, a month after Russia annexed the Crimea peninsula.
Almost 5,800 people have died since then, the UN has estimated, although it believes the real figure could be considerably higher.
The two sides say they are now withdrawing their heavy weapons from the front line under a truce deal.
