Salah Abdeslam, the main fugitive from Islamic extremist attacks in Paris in November, was arrested in Belgium's capital Friday after four months at large, two French police officials told The Associated Press.

They said he was arrested in a major police operation in the Brussels neighborhood of Molenbeek. Both officials are in contact with people involved in the operation and spoke on condition of anonymity because they were not authorized to speak publicly about an ongoing operation.

Theo Francken, Belgium's secretary of state for asylum and migration, tweeted, "We hebben hem," which translates to English, "We got him."

The arrest would be a dramatic tu in the investigation that has vexed European officials for months.

Abdeslam fled Paris after the Nov. 13 gun and bomb attacks that killed 130 people at a theatre, the national stadium and cafes. Most of the Paris attackers died that night, including Abdeslam's brother Brahim, who blew himself up. The Islamic State terror group claimed responsibility for the attacks, in which Belgian nationals played key roles.

There are few details about the raids. Francois Schepmans, the mayor of Molenbeek, said two people were injured in the operation.

French president Francois Hollande told reporters in Brussels he would not give details on the "operation that is under way."

As Friday's events unfolded, Belgian Prime Minister Charles Michel rushed out of a European Union summit, and was expected to be joined at Belgian govement offices by Interior Minister Jan Jambon, RTBF said.

In Tuesday's raid, two people escaped from the home in the Forest neighborhood of Brussels, but Belgian federal prosecutor Eric Van der Sypt said it wasn't yet known if Abdeslam was one of them. He also said it hasn't been established how old the fingerprints were, or how long Abdeslam spent in the apartment on the Rue Du Dries.

Police who raided the apartment Tuesday found an ISIS banner as well as 11 Kalashnikov loaders and a large quantity of ammunition, the prosecutor said.

A man was shot dead by a police sniper there as he prepared to open fire on police from a window. Police identified him as Mohamed Belkaid, 35, an Algerian national living illegally in Belgium.

A Kalashnikov assault rifle was found by his body, as well as a book on Salafism, an ultraconservative strain of Islam.

Police who went to search the apartment "were not expecting a violent armed reaction," Prime Minister Charles Michel said.

Four officers, including a French policewoman, were slightly wounded when they were shot at as they opened the door.

Abdeslam slipped through a police dragnet to retu to Brussels after the Paris attacks, and though he is the target of an inteational manhunt, has not been seen since.

In January, Belgian authorities said one of his fingerprints was found alongside homemade suicide bomb belts at an apartment in another area of Brussels. Belgian prosecutors said it wasn't known whether he had been at the address in the Schaerbeek district before or after the Paris attacks, or how long he had spent there.
