Which is not closely related out of Leningrad Moscow El Alamein and Stalingrad?

Leningrad, Moscow, and Stalingrad are all cities in Russia that were significant during World War II, particularly in relation to battles fought on the Eastern Front. El Alamein, on the other hand, is a town in Egypt known for its battles in the North African campaign during the same war. Therefore, El Alamein is not closely related to the other three cities.
