Two stand-offs involving hostages came to a violent denouement in Paris and at an industrial building miles away from the country's main airport.

:: After an hours-long stalemate, gunfire and explosions were heard at a print works in Dammartin-en-Goele, some 30 miles northeast of the city.

:: Two brothers were holed-up there after being hunted by police over the Charlie Hebdo magazine killings in the capital on Wednesday. Said and Cherif Kouachi, (aged 34 and 32) came out firing when police stormed the building they were in and authorities have confirmed they were killed.

:: Minutes later at a kosher grocery in east Paris, the siege in Paris was also reaching a bloody end with the death of at least three hostages and a jihadist gunman.

:: The Kouachi brothers had a 26-year-old man as a hostage. A local MP told media the "fugitives have said they want to die as martyrs".

:: Their confrontation with police came after a 48-hour manhunt during which almost 90,000 French police officers and soldiers were mobilised for the manhunt.

:: The brothers had fled the capital on Wednesday after their attack, in which they stormed the offices of the satirical magazine before shooting dead a police officer in the street.

:: On Thursday there were reports the pair had been spotted at a petrol station roughly a 25-minute drive northeast from Dammartin-en-Goele where the owner recognised the two brothers.

:: After robbing the station and hiding in a nearby forest overnight, they hijacked a Peugeot 206 from a woman, who also recognised them, and headed south on a motorway on Friday morning.

:: As officers chased and cornered them at the printing factory, residents were told to stay at home, switch off the lights and stay away from their windows. Schools were evacuated and the airport closed two runways at Charles de Gaulle airport, seven miles away from the scene.

:: The Kouachis were understood to have links to those behind the supermarket attack, who were also said to be involved in the shooting of a policewoman in the south of Paris a day earlier. Mugshots of Amedy Coulibaly and his partner since 2010, Hayat Boumeddiene, were released in relation to the killing of the officer in an attack that also left a street sweeper in a critical condition.

:: At the kosher supermarket, SWAT teams, dozens of police vans and emergency services were backed up by helicopters and snipers watching from a building.

:: Israeli TV says a six-month old baby and the baby's mother were among those held captive, although the number of hostages remains unclear. AP reported that the gunman had threatened to kill his hostages if police stormed the brothers at the scene in Dammartin-en-Goele.

:: After the sieges had ended, France's President Francois Hollande praised the bravery of police and said: "Long live the Republic and long live France", but he warned the threats facing France "weren't over".

:: The United States warned of a global threat, telling its citizens to beware of "terrorist actions and violence" all over the world.

:: A member of al Qaeda's branch in Yemen says the group directed the attack on Charlie Hebdo.

:: Paris prosecutor Francois Molins says an employee at the printing works where the Kouachi brothers were in Dammartin-en-Goele was hiding on the second floor underneath a sink. The brothers did not realise there was another person hiding in the warehouse.

:: Mr Molins went on to reveal that Boumeddiene and the partner of one of the Kouachi brothers had called each other more than 500 times last year.

:: He also said the four hostages found dead in the kosher supermarket were not likely to have been killed by police forces.

:: Key members of the French government are holding an emergency meeting on Saturday to decide on new measures aimed at thwarting a repeat of the attacks.
