A number of arrests have been made in Belgium over terrorist attacks in Paris which have killed at least 129 and left several hundred more injured.
The Belgian justice minister confirmed that a number of arrests had been made in Brussels in relation to the attack.
The Sydney Morning Herald reports that three of the Paris attackers lived in the same neighbourhood in Brussels and a car used in the attacks was registered in Belgium.
In the deadliest violence witnessed in Europe in decades, more than 100 people were slain at the Bataclan theatre after gunmen took hostages.
French security forces raided the concert theatre, which was hosting an American rock band, killing two assailants. Speaking with The Guardian after escaping the Bataclan, a man described the scene as "carnage," adding there were "bodies everywhere."
Eight extremists were killed in Paris, including seven in suicide bombings.
Two explosions occurred outside the Stade de France stadium north of Paris during a friendly match between France and Germany, killing three people. The police later confirmed these were suicide attacks. The sound of the explosions was captured by cameras filming the match. French president Francois Hollande, who was in attendance, was evacuated from the ground.
Mr Hollande has called the attacks "an act of war" and said France would observe three days of mourning.
Overnight, a Paris prosecutor said there were three teams of terrorists involved, who had struck in coordinated attacks across the city.
Islamic State has claimed responsibility for the attacks in a statement posted online.
“Eight brothers, wrapped in explosive belts and armed with machine rifles, targeted sites that were accurately chosen in the heart of the capital of France,” the online statement said.
“Let France and those who walk in its path know that they will remain on the top of the list of targets of the Islamic State.”
