Police and security agencies in multiple countries scramble to piece together background and intentions of Hamam al-Hammami

Investigators believe the co-pilot who tried to take control of a plane from Dubai to Tel Aviv last week originally planned his attack for July but postponed the hijacking, possibly because a friend was among the crew, regional and Israeli officials have said.

The evidence of prior planning suggests that Hamam al-Hammami, 29, may have specifically sought employment with an airline that flew to Israel in order to carry out the attack on last Wednesday’s flydubai ‌flight FZ1073, experts believe.

Twenty-five years after 9/11, figures compiled by conflict monitor underline how Sahel region has become centre of Islamist terror

Islamist extremist violence in Africa’s Sahel region is set to reach historic highs after a series of sweeping offensives by groups linked to al-Qaida and Islamic State, according to new figures compiled by the conflict monitor Acled.

As the US marks the 25th anniversary of the 9/11 attacks launched by al-Qaida against targets in Washington and New York, the statistics underline the continued expansion of the veteran organisation in parts of Africa – in stark contrast with its relative weakness elsewhere.

The presidential briefing documents were declassified on the 25th anniversary of the September 11 attacks

Several dozen presidential briefing documents declassified on Friday, the 25th anniversary of the September 11 attacks, detail intelligence that government officials had gathered about Osama bin Laden and al-Qaida leading up to the hijackings that killed nearly 3,000 people and upended American national security.

The documents illustrate security analysts’ tracking of Bin Laden’s movements and support system, as well as concerns about possible threats to US targets. They also detail officials’ understanding of his network in the United States and other countries, including how his operations were financed.

The al-Qaida leader envisaged an economically battered US withdrawing from the Middle East – and a global Muslim uprising. Then the tide turned

On 11 September, 25 years ago, Osama bin Laden drove with a small number of al-Qaida retainers and aides to a remote location in eastern Afghanistan. His convoy of SUVs was accompanied by a minivan converted into a makeshift communications centre.

The van’s rudimentary equipment did not allow Bin Laden to watch the 19 men he had started sending to the US more than a year before fly planes into the twin towers in New York and the Pentagon near Washington DC, killing about 3,000 people. But he listened as shocked radio announcers broke the news.

Coordinated attack by JNIM and the Tuareg minority inflicted significant casualties on government forces and Russian auxiliaries

When al-Qaida-affiliated Islamic militants launched a series of attacks on military bases and raids into major towns in Mali and neighbouring Burkina Faso last summer, observers suggested they had been inspired by their counterparts in Syria, who had overthrown the regime of Bashar al-Assad and taken power six months or so earlier.

Despite the tactical successes that earned them the fearful title of the “Ghost Army”, seizing swathes of territory and denying cities and the military of fuel and other essentials, the chances of Jama’at Nusrat ul-Islam wa al-Muslimin (JNIM) definitively defeating Mali’s military regime and the thousand or so Russian mercenaries hired to defend it looked poor.

Russian backing for the ruling junta has not stopped rebel fighters striking significant blows in recent days

• Mali in turmoil after insurgents seize towns and kill defence minister

When Assimi Goïta, the leader of Mali’s military junta, sat down with the Russian president, Vladimir Putin, in the Kremlin last summer, it symbolised Moscow’s commanding sway over Mali at the expense of the west.

As the two men spoke, roughly 3,500 miles to the south, about 2,000 Russian troops were propping up the regime in the landlocked desert country, as part of Moscow’s broader push for influence across the Sahel region.

Military intelligence chief reportedly also killed in sweeping attacks by jihadists and separatist rebels

Mali has been left reeling from sweeping attacks by jihadists and separatist rebels who seized several towns and military bases and killed the defence minister and military intelligence chief.

The weekend assault on the west African state’s security architecture was coordinated by al-Qaida-affiliated Jama’at Nusrat al-Islam wal-Muslimin (JNIM) and the separatist Tuareg-led movement Azawad Liberation Front (FLA) – former foes with distinct agendas.

Car bomb kills Sadio Camara at home during coordinated assaults by rebel groups including West African al-Qaida affiliate

Mali’s defence minister was killed in an attack on his residence, the government said on Sunday, a high-profile fatality during coordinated assaults staged the previous day by insurgents including the West African affiliate of al-Qaida.

A car laden with explosives driven by a suicide attacker drove into Sadio Camara’s residence in the town of Kati, the spokesperson, Issa Ousmane Coulibaly, said in a statement read out on state television. A firefight ensued, and Camara sustained injuries from which he later died in a hospital, Coulibaly said, adding that Mali would observe two days of mourning.

Al-Qaida-linked group JNIM claims responsibility for strikes on airport in capital, Bamako and four other cities

Islamic militants and separatists attacked several locations in Mali’s capital and other cities on Saturday in one of the largest coordinated attacks in the country in recent years.

The al-Qaida-linked militant group JNIM claimed responsibility for the attacks on Bamako’s international airport and four other cities in central and northern Mali on its website, Az-Zallaqa. It said the attacks were carried out jointly with the Azawad Liberation Front, a Tuareg-led separatist group.

Former attorney general urges more clarity on British spy agencies’ role in Abu Zubaydah’s torture by CIA

Ministers should explain why the UK has paid compensation to a Palestinian man who was tortured by the CIA and is still being held in Guantánamo Bay, according to a former attorney general.

Abu Zubaydah, the first man subjected to CIA waterboarding, was reported by the BBC to have been awarded a payment that may amount to hundreds of thousands of pounds because of the role of MI5 and MI6 in his mistreatment.
