I don't remember anything about French aircraft raiding Palestine during the Syria campaign: they flew bombing sorties mainly (if not only) against British ships and Allied troops on or close the battlefield. They flew recon sorties over Palestine on the other hand.
No German or Italian bombers were based in Syria, but they flew sorties in the area during this period, and wikipedia has the following (that should be checked, of course...):
"There was even another small bombardment of Tel Aviv in June 1941, done by the Italians together with some airplanes of the German
Luftwaffe." given source:

According to this, the second raid was on 12 June 1941.
The link below is precising that a bomb hit a invalid home, killing 12 and wounding others, three of which died later. There is also the list of the people killed and wounded.
