For goodness sake! Dozens of aircraft divert every day for one reason or another. Most are medical diversions. Some are technical but not to the extent that they have to divert to the nearest airport. Technical problems can be of a nature which, for a variety of reasons already explained many times on these forums, requires the aircraft to return to it's base airport, departure airport or an airport where they have engineers and spares at hand.
But aren't we talking about a medical emergency here, not a base airport, departure airport, or an airport where they need engineers or spares. It also appears that Kuwait Airlines flys to and from FRA anyway. I only asked why London, and is what rhetorical, as I'm sure that you, nor anyone on here, doesn't have the answer.
