KABUL • French and Algerian fighters, some arriving from Syria, have joined the ranks of ISIS in northern Afghanistan, where the militants have established new bases, multiple international and Afghan sources said.
It is the first time that the presence of French Islamic State in Iraq and Syria (ISIS) fighters has been recorded in Afghanistan, and comes as analysts suggested foreigners may be heading for the war-torn country after being driven from Syria and Iraq.
It is also a troubling sign as France, which has faced the worst of the ISIS-inspired violence in Europe since 2015, debates how to handle hundreds of its citizens who went to fight for the militant group in the Middle East.
"A number" of Algerian and French nationals entered the largely ISIS-controlled district of Darzab in northern Jowzjan province last month, said district governor Baaz Mohammad Dawar.
At least two women were among the arrivals, who were travelling with a translator from Tajikistan as well as Chechens and Uzbeks, Mr Dawar added.
European and Afghan security sources in Kabul confirmed Mr Dawar's claim that French citizens were among the fighters - though, one cautioned, "we do not know how many there are".
Three of the Algerians seen in Darzab are believed to have been in Syria and Iraq, Mr Dawar said, suggesting they may link Islamic State-Khorasan Province (IS-K), the group's franchise in Afghanistan and Pakistan, with the main group in the Middle East.
Darzab residents said that roughly 200 foreigners had set up camp just a few hundred metres from the village of Bibi Mariam. One local man who gave his name as Hajji said the fighters were of several nationalities, including French, and were tall, aged in their late 20s, and dressed in military clothing.
When it first emerged in 2015, IS-K overran large parts of eastern Nangarhar and Kunar provinces, though initially its part in the Afghan conflict was overshadowed by the Taleban.
The extremists have since spread north, including in Jowzjan on the border with Uzbekistan, and carried out multiple devastating attacks in the capital Kabul.
Mr Mohammad Raza Ghafoori, the Jowzjan provincial governor's spokesman, said French-speaking Caucasian men and women had been seen training ISIS fighters in Darzab. He cited reports saying that around 50 children, some as young as 10, have also been recruited by the militants.
Darzab residents told Agence France-Presse (AFP) that roughly 200 foreigners had set up camp just a few hundred metres from the village of Bibi Mariam.
One local man who gave his name as Hajji said the fighters were of several nationalities, including French, and were tall, aged in their late 20s, and dressed in military clothing.
A former district village chief, known only as Mr Hashar, said some were training others to use suicide bombs and lay mines.
Locals, along with district governor Mr Dawar, warned the fighters were also exploiting natural resources, such as precious stones and metals.
One of the security sources said that two of the French had been nicknamed "The Engineers" and appeared to be organising some sort of extraction, "but we do not know what they are looking for".
Several European services believe the fighters are arriving through Tajikistan, the source said, adding that at least one Frenchman arrested there in July said he had wanted to join ISIS in Afghanistan.
Afghanistan has long attracted foreign fighters, from the mujahideen during the 1980s war against Soviet invaders to Al-Qaeda's later use of the country as a haven.
The Pentagon has said ISIS numbers are fewer than 1,000 in Afghanistan.
But the growing presence of foreign fighters among them indicates that ISIS "seeks to create an external operations node for new waves of global attacks", warned analysts at the Washington-based Institute for the Study of War recently.
Mr Aymenn Jawad Al-Tamimi, an expert on Muslim extremist groups, said he did not think the presence of foreign fighters in Afghanistan meant that ISIS was necessarily "shifting its base".
The group's "natural home is Iraq and Syria, but I presume many of the foreigners in particular are taking the opportunity either to escape entirely or moving to other battlefields for ISIS where they might prove more useful", he told AFP.
The head of US forces in Afghanistan, General John Nicholson, has vowed the group will be "annihilated", and Washington notoriously dropped the so-called "mother of all bombs" on an ISIS stronghold in Nangarhar in April.
But as the number of fighters grows in Darzab, the villager Hajji told AFP there were no signs of pro-government forces in the district.
"There is no government here," he said.
