A British man has been handed a life sentence for conspiring to attack a military training institution, a plot that investigators say was connected to a subsequent deadly stabbing at a synagogue. Mohammad Bashir, 31, pleaded guilty at Manchester Crown Court to preparing an act of terrorism and must serve a minimum of 17 years before being eligible for parole.
The case emerged from the investigation into the October 2024 attack on a synagogue during Yom Kippur, carried out by Bashir’s associate, Jihad Al-Shamie. While Bashir was not directly involved in that assault, evidence uncovered on phones seized from Al-Shamie revealed that the two men had jointly planned a similar attack on the UK’s Defence Academy in Shrivenham, Oxfordshire. They believed the academy trained Israeli forces.
“Mohammad Bashir is a determined jihadist and dangerous individual who was planning an attack that could have caused devastation,” the Crown Prosecution Service stated. “His actions demonstrate a deliberate and sustained commitment to violent extremism.”
Scouting the Target
Two months before the synagogue attack, Bashir drove Al-Shamie from Manchester to the Defence Academy to reconnoitre the site. The pair discussed entry methods, weapons, and the use of a fake suicide vest to maximise casualties. Justice Bobbie Cheema-Grubb told Bashir during sentencing: “I am sure that you and he anticipated that you would both be martyred and you intended to kill others. This was a viable plan to attack the Defence Academy in a broadly similar way to that in which Al-Shamie attacked the synagogue; using handheld weapons and a dummy suicide vest to cause as much bloodshed as possible.”
The planned attack was never executed, and prosecutors confirmed no evidence linked Bashir to the synagogue stabbing. However, the case has raised serious questions about intelligence sharing and police oversight. Greater Manchester Police acknowledged on Thursday that messages between the two men were found on phones seized from Al-Shamie after earlier arrests in 2025 but were not reviewed before the synagogue attack. Chief Constable Stephen Watson apologised, calling it “a missed opportunity.” The Independent Office for Police Conduct is now examining whether the overlooked data could have prevented the tragedy.
This incident underscores broader security challenges across Europe. Lone-actor terrorism remains a persistent threat, as highlighted in recent Europol warnings. The case also echoes other violent episodes on the continent, such as the knife attack at the Athens Acropolis that injured two tourists, though motivations differ.
Bashir left the UK two days after the synagogue attack and was arrested at Manchester Airport in November 2025 upon returning from a family wedding in Pakistan. His sentencing marks the conclusion of a case that has exposed vulnerabilities in counter-terrorism procedures and the enduring threat of extremist violence within the United Kingdom.
