Dozens of reservists from the Israeli military’s Medical Corps have declared their refusal to return to combat in Gaza, Al Jazeera reports, citing Israel’s Kan public broadcaster.

Citing a letter on the subject seen by the news outlet, Kan said the reservists refused to return over ethical and legal concerns, as well as the extension of the conflict “beyond all reason”.

The letter, signed by medical professionals of various ranks — including doctors, paramedics, mental health officers and nurses — said the offensive is causing harm “to civilians on both sides, to Israel’s social fabric, and to the country’s long-term survival”.

The letter also noted that “the takeover of [Palestinian] territories and the call to settle them” stands in “violation of international law”.
