The whole (brief) press release is worth reading IMO, but here's a snippet:
ICJP LWGCA [International Council of Jewish Parliamentarians International Centre of Justice for Palestinians Legal Working Group for Canadian Accountability] calls on the Government of Canada to end its complicity in war crimes by calling for a ceasefire, canceling all arms exports permits to Israel, prosecute those recruiting Canadian volunteers for Israel’s armed forces, and prevent Canadian charities from using donations to benefit Israel’s armed forces.
I appreciate the correction - you're completely right. The group behind this is indeed, International Centre of Justice for Palestinians. I overlooked the fact that the different groups might use the same acronym - not my brightest moment. Thank you for pointing this out!
