Disagreed, this makes it sound like 70000 of them are possible combatants. They could have easily cited a source clarifying that 2/3 of them are women and children or so.

Also military service is obligatory in Israel with few exceptions, so you could argue that most of the people killed at an 18+ festival were also likely (unmarked) combatants.

The typical reader will skim the article and read "Hamas killed 1000 civilians, Israel killed 70000 combatants." and it is intentionally worded that way.
