From the article: »Cities will probably target models with older emission controls. Of the 15 million diesel cars on Germany’s roads, only 2.7 million have the latest Euro-6 technology, data by the KBA motor vehicle watchdog showed.«

I think cities are only interested in banning older diesels that don't meet Euro-5 or Euro-6.

Diesel cars have been under fire for quite some time because auto makers across the entire industry cheat on emission tests: https://en.wikipedia.org/wiki/Diesel_emissions_scandal

Generally they are not. Newer ones are within limits set acceptable by emission standards, but those standards don't really model real world use where their performance is generally atrocious.
I happen to be (now not very happy) owner of a diesel car.

It’s backed by science. Due to the high temperatures in a Diesel engine, the amount of NOx produced is far higher than for petrol cars. NOx can be handled by a catalysator using AdBlue or similar, so in theory Diesel engines could be clean. In practice the standards are routinely ignored by the car makers.
The ruling allows banning cars that do not fulfil current standards, so a recent car is probably unaffected. However, the restriction could be lifted if only banning old cars proves insufficient. Then, newer cars could be affected.

They emit less of the greenhouse gas CO_2 than gasoline engines, but often more unhealthy nitrogen oxides and particulate matter.

Yes it is. It is not about CO2 emissions, where Diesel engines are indeed more efficient than petrol engines, but about the "fine dust" emitted by a highly charged turbo setup, like most modern Diesel layouts are...
