On 7 January 1957, Governor-General Robert Lacoste summoned General Salan and General Massu commander of the 10th Parachute Division (10e DP) and explained that, as the Algiers police force was incapable of dealing with the FLN and controlling the Pied-noirs, Massu was to be granted full responsibility for the maintenance of order in Algiers.
On the afternoon of Saturday 26 January, female FLN operatives again planted bombs in European Algiers, the targets were the Otomatic on Rue Michelet, the Cafeteria and the Coq-Hardi brasserie. The explosions killed 4 and wounded 50 and a Muslim was killed by Pied-Noirs in retaliation.
In late January the FLN called an 8-day general strike across Algeria commencing on Monday 28 January. The strike appeared to be a success with most Muslim shops remaining shuttered, workers failed to turn up and children didn't attend school. However Massu soon deployed his troops and used armored cars to pull the steel shutters off shops while army trucks rounded up workers and schoolchildren and forced them to attend their jobs and studies. Within a few days the strike had been broken.
On 9 February, paratroopers of the 2nd Parachute Chasseur Regiment (2e RCP) arrested a prominent young lawyer and FLN sympathiser Ali Boumendjel. After attempting suicide Boumendjel volunteered everything he knew, including his involvement in the murder of a European family.
While females had not previously been searched in Algiers; following the Coq Hardi explosion one of the waiters identified the bomber as a woman. Accordingly, female suspects were subsequently searched by metal detectors or physically, limiting the ability of the FLN to continue the bombing campaign from the Casbah. In February Bigeard's troops captured Yacef's bomb transporter, who under extreme interrogation gave the address of the bomb factory at 5 Impasse de la Grenade. On 19 February the 3e RPC raided the bomb factory finding 87 bombs, 70 kg of explosives, detonators and other material, Yacef's bomb-making organisation within the Casbah had been destroyed.
On 23 March following a meeting between Massu, Trinquier, Fossy-Francois and Aussaresses to discuss what was to be done with Ali Boumendjel, Aussaresses went to the prison where Boumendjel was being held and ordered that he be transferred to another building, in the process he was thrown from a 6th floor skybridge to his death.
The use of torture was not restricted to Muslims, French FLN sympathisers were also picked up and subjected to it. Maurice Audin a Communist university professor was arrested by the paras on 11 June on suspicion of harboring and aiding FLN operatives, Henri Alleg the Communist editor of Alger républicain was arrested by the Paras at Audin's apartment the following day and was told by Audin that he had been tortured, Audin was never seen again and it is believed that he either died while being interrogated or was summarily executed.
On 3 June Yacef's forces planted bombs in street lamps at bus stops in the centre of Algiers, the explosions killed eight and wounded 90, a mix of French and Muslims., the explosions killed eight and wounded 90, a mix of French and Muslims.
On 9 June a bomb exploded at the Casino on the outskirts of Algiers killing nine and injuring 85. Following the burial of the dead from the casino, the Pied-Noirs started a ratonnade that resulted in five Muslims dead and more than 50 injured. As a result of this upturn in violence the 10e DP was again deployed to Algiers.
On 26 August following intelligence gained by Colonel Godard's operatives, the 3e RPC raided a house in the Impasse Saint-Vincent where Yacef's new bomb-maker and deputy were believed to be hiding. After suffering several casualties trying to capture the two alive, both men were eventually killed.
At 5am on 24 September the 1e REP commanded by Colonel Pierre Jeanpierre sealed off Rue Caton and raided Yacef's hideout at No. 3. Yacef and Zohra Drif hid in a wall cavity, but this was soon located by the French troops. Yacef threw a grenade at the French troops but they were eager to take him alive and he and Zohra Drif eventually surrendered. Across the street at No 4, Ali La Pointe escaped the French cordon and went to another safe-house in the Casbah.
On the evening of 8 October the 1e REP surrounded Ali La Pointe's hideout at 5 Rue de s Abderames. The paratroops laid charges to blow away the false partition behind which Ali and his comrades were hiding, unfortunately the explosion detonated a store of bombs destroying the house and several neighbouring buildings, killing Ali, his two comrades and 17 other Muslims in neighbouring houses.
