One of the suspected ringleaders of last month's Paris attacks, Salah Abdeslam, traveled to Hungary where he "recruited a team" from unregistered migrants passing through, senior Hungarian government officials said Thursday, according to AFP.

"I can confirm that one of the main organizers of the Paris terror attacks was in Budapest," Prime Minister Viktor Orban's chief of staff Janos Lazar told a regular news conference in Budapest.

Lazar did not name the man or say when he was in Hungary, nor whether those he picked up went on to take part in the November 13 attack in the French capital claimed by the Islamic State (ISIS) group.

But speaking to AFP on condition of anonymity, a government source later confirmed that the man was in fact Abdeslam, a main suspect in the attacks who is currently on the run.

Lazar had said the suspect had been in Keleti station in Budapest, "recruiting a team from immigrants who had refused to register with Hungarian authorities", referring to migrants.

He then "left the country together with them," Lazar added, according to AFP.

A French source familiar with the investigation told AFP that a car rented by Abdeslam is known to have been in Hungary on September 17.

It was unclear however, whether Abdeslam, who played a key role in the Paris attacks in which 130 people were killed, was himself in the vehicle, and if so, whether he was accompanied, the source added.

There has been a manhunt for Abdeslam, 26, ever since the November 13 attacks. He was not one of 16 suspects arrested in 19 recent raids by the Belgian security forces, and it was later speculated that he fled from Belgium to Germany.

Abdeslam was also registered as having been in Austria on September 9 after being stopped in a routine traffic check, Austrian authorities said on November 17.

He and two other men were stopped in a car with Belgian number plates after travelling south from Germany, not west from Hungary.

Abdeslam told police he was "on holiday".

Austrian authorities last month said that the two others "have so far not been named in connection" with the Paris attacks.
