This means the trucks were bombed intentionally, they were bombed when clearly identified as aid workers, or they were bombed indiscriminately.

This is just more business as usual.

From the UN (2019):

More than 6,000 unarmed demonstrators were shot by military snipers, week after week at the protest sites by the separation fence.

The Commission investigated every killing at the designated demonstration sites by the Gaza separation fence on official protest days. The investigation covered the period from the start of the protests until 31 December 2018. 189 Palestinians were killed during the demonstrations inside this period. The Commission found that Israeli Security Forces killed 183 of these protesters with live ammunition. Thirty-five of these fatalities were children, while three were clearly marked paramedics, and two were clearly marked journalists.
