Definitely whataboutism, but the crew were investigated before the leak and it was found that the reporters were with armed fighters and were not distinguishable as civilian reporters. While its unfortunate, walking around in an active warzone with armed combatants and not taking steps to clearly identify yourself as a non combatant isn't wise. These things happen in war. They were not intentionally targeted and they weren't murdered. War reporters know the risk they are taking on and this is why they usually clearly mark themselves as press.
