In the Nasser Medical Complex in Gaza’s Khan Younis, a volunteer doctor breaks down as he speaks of what he has seen during his mission amid Israel’s unabated bombardment, reports Al Jazeera.

It’s a feeling echoed by the three other doctors to whom Al Jazeera spoke. Orthopaedic surgeon Anas Hijjawi described a long line of doctors who had signed up for medical missions to Gaza, some of whom had to wait up to five months for a spot to open up.
