BRUSSELS, Begium (UPDATED) – Belgian police found an Islamic State (ISIS) flag next to the body of an Algerian killed during a raid in Brussels, investigators said Wednesday, March 16, as they raced to track down two suspected extremists who escaped.
In Paris, meanwhile, French police said they had arrested 4 suspected Islamists, one of whom was believed to be plotting attacks, and President Francois Hollande urged the public to be vigilant.
Belgian investigators named the fatality in the Brussels operation as Mohamed Belkaid, 35, an Algerian national living illegally in Belgium, who was killed by a police sniper while trying to fire at police during a chaotic gunbattle on Tuesday, March 15.
Two suspects were still at large after the bloodshed, which erupted as Belgian and French police searched a property in connection with the November 13 Paris massacres, claimed by ISIS, in which 130 people died.
Belgian Prime Minister Charles Michel said authorities had decided to maintain the country's terror alert at the second-highest level of 3, "which means a threat is possible and likely".
Brussels was locked down and the alert level raised to the highest of four shortly after the Paris attacks, but it was lowered back to three a few days later, although troops remain outside many key sites.
Rifle and flag
Prosecutors said at least two armed suspects fired on police as the door was opened during a search of the property in the quiet Forest district in southern Brussels, wounding 3 officers including a French policewoman.
After hours of gunbattles in which a fourth officer was hurt, a suspect was "neutralized by a sniper of the special forces when he tried to open fire from the window of the flat," spokesman for the prosecutors Thierry Werts said.
"Next to his body was a Kalashnikov, a book on Salafism (an extreme form of Islam) and an Islamic State flag," Werts told a press conference. Eleven magazines of ammunition for Kalashnikov assault rifles were also found.
Belkaid was unknown to Belgian authorities except for a case of minor theft in 2014, they said.
Werts said that "two persons who were probably in the flat and whose identity is not known fled the scene and are being tracked down".
A second Kalashnikov and black clothes were found abandoned at a house nearby but searches throughout the southern district of Brussels for the two men yielded "no results", he said.
Two suspects arrested in connection with the case, including one found in hospital with a broken leg, were later released without charge, prosecutors added.
Belgian media reported that the two missing suspects were brothers with links to terrorism but there was no immediate confirmation.
Brussels extremist history
Belgium has been at the center of the investigation into the Paris attacks almost from day one.
Key Paris suspect Salah Abdeslam fled to Brussels after the attacks and is believed to have holed up in a flat for at least 3 weeks. He remains on the run while his brother Brahim blew himself up in the massacre.
The ringleader of the attacks, ISIS member Abdelhamid Abaaoud, was also from Brussels. He was killed in a raid in Paris in November.
Both had links to the largely immigrant Brussels district of Molenbeek which was targeted by authorities after the attacks.
Meanwhile in Paris 4 suspected islamists were arrested Wednesday, one of whom was thought to be planning "violent acts", French Interior Minister Bernard Cazeneuve said.
"This individual may have been in contact with individuals in Syria belonging to Islamic State," Cazeneuve said. The jihadist group is also known by the acronyms of ISIL and IS or Daesh.
Cazeneuve downplayed reports that the attack had been "imminent" and said the authorities "carry out arrests of this kind every day."
Hollande, though, called for the public to exercise "the greatest vigilance."
"The threat level remains very high," said Hollande. "(...) We know that we are a target. France was also the target in what happened in Ivory Coast," said Hollande, referring to Sunday's assault on a beach resort near Abidjan that left 19 dead, four of them French nationals.
The four – 3 men and a woman – had been under surveillance by French intelligence on suspicion of a "possible plan to attack", police sources said.
Police raids turned up no weapons, but computer hardware and data have been seized for analysis, they said. – Danny Kemp and Alex Pigman, AFP / Rappler.com
