What is the right course of action?

You correctly chose to wait because the two pedestrians have priority. According to German traffic rules, pedestrians on a marked or designated crossing, or where they have clear right of way, must be allowed to cross safely before you proceed.

In this situation, even if you are turning, pedestrians crossing ahead have the right of way. It is your responsibility as a driver to yield and wait until they have fully crossed. This rule ensures pedestrian safety and helps prevent accidents.

Continuing to drive without waiting would be a violation of these right-of-way rules, and assuming only one pedestrian must wait is incorrect because both are on the crossing and both have priority. Always give priority to pedestrians crossing or about to cross in front of your vehicle.
