The two suspects in the terror attack at Paris magazine, Charlie Hebdo, were killed Friday as police assaulted the building where they had holed up near Charles de Gaulle Airport, at Dammartin-en-Goele, about 26 miles northeast of central Paris.
Another hostage taker was also killed by the police in a store in eastern Paris in another incident.
Security forces, which had earlier sealed off the area, surrounded the industrial park where two terror suspects who attacked the magazine on Wednesday, were operating from, for most of Friday, cornering the two brothers.
Explosions and gunshots were heard as security forces made efforts to rescue the hostages and apprehend the suspects.
In a related incident, intense gunfire and explosions were also reportedly heard at the grocery store in eastern Paris where a gunman had taken hostages.
The coordinated police assaults were as a result of the threats issued by the gunman in Paris to kill as many hostages as he could if police stormed the industrial park in Dammartin-en-Goele.
Hostages were freed at both sites. However, the gunman is believed to have killed four hostages at the supermarket and injured some others.
The brothers, Cherif and Said Kouachi, were suspected to have killed 12 people at the Paris offices of the satirical weekly magazine on Wednesday.
