From the same article:

>Independent analysis of satellite imagery suggested that the school and the Sayyid al-Shuhada military complex had been struck near-simultaneously by air-delivered munitions.[39]

The objectionable part of double/triple tap strike is that you're killing rescuers or aid workers. Otherwise from a morality perspective there's no meaningful difference between 1 bomb and 2/3 bombs, especially if the actual incident was by all accounts caused by a targeting error.

Triple tap seems to indicate definitely a mistake in targeting.

Despite the war aims being nebulous, illegal, and ever changing, none of them would be advanced by bombing a girls school.

I would like the Iranian regime to be destroyed more responsibly and carefully.

Triple, according to Wikipedia.
