Which indicate radar lock on something (my guess cruise missile) and a "hit" at least according to the fire control radar...
Could the something be a MALD or MALD-J?
No point deploying MALD, as there was no higher value target to deflect attention from.
But they would soak up SAMs and otherwise distract the defences. MALD's unit cost is $30000 to $332000 depending on version (the initial A version was bought in tiny quantities) according to Wiki so still a lot less than even a Tomahawk. Also, in this case, the success of the mission was probably deemed more valuable than the cost of the missiles employed.
