Let's try to par with 9/11 

7 July 2005 London bombings →  – we wouldn't write the "September 11 attacks" as "September 11, 2001 attacks" and my proposed title will actually make a reference to WP:COMMONNAME, as this bombing spree is usually known simply as "7/7" (like "September 11", aka "9/11"). Most media coverage also refers to this as "7/7": see this BBC report on the inquest, this article on CNN, the Sky News articles "7/7 London Bombings: Terror Arrest" and "7/7-Style Explosives Found In NY Cemetery", The Guardian's "Thousands to mark anniversary of 7/7 London bombings" article, the "7/7 Tavistock Square bus bomb" report seen on Newsnight and "Is London ready for another 7/7?" to see a few. Google News has the results as is: 1,600 for "7 July 2005 London bombings" and 1,960 for "7 7 London bombings". Therefore, amalgamate "7/7" as the common name and "London bombings" as the description together in the article title and that will make thie article seem more like "September 11 attacks" in terms of naming.  92.4.75.68
