21 July 2005 London attempted bombings
attempted terrorist attacks in London
On 21 July 2005, four attempted bomb attacks by four Islamist extremists disrupted part of London's public transport system as a follow-up attack to the 7 July 2005 London bombings two weeks earlier. The explosions occurred around midday at Shepherd's Bush, Warren Street and Oval stations on the London Underground, and on London Buses route 26 in Haggerston. A fifth bomber dumped his device without attempting to set it off.
Connecting lines and stations were closed and evacuated. Metropolitan Police later said the intention of the attack was to cause large-scale loss of life, but only the detonators of the bombs exploded, probably causing the popping sounds reported by witnesses; a person having a minor asthma attack was the only reported injury. The suspects fled the scenes after their bombs failed to explode.
The next day, Friday, 22 July 2005, CCTV images of four suspects wanted in connection with the bombings were released. Two of the men shown in these images were identified by police on Monday, 25 July 2005 as Muktar Said Ibrahim and Yasin Hassan Omar. The resulting manhunt was described by the Metropolitan Police commissioner Sir Ian Blair as "the greatest operational challenge ever faced" by the Met. During the manhunt, police misidentified a Brazilian citizen, Jean Charles de Menezes, as one of the suspected bombers and shot him dead.

Why this record matters
The phrase “attempted terrorist attacks in London” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Aug 30, 2026. The linked authority identifier is Q2870041. Authority coordinates are 51.528, -0.076. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 2005.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
