Multiple humanitarian aid flotillas bound for Gaza were intercepted by Israeli forces in May 2026, leading to international condemnation over alleged mistreatment of detained activists. South Korean activists Kim Dong-hyeon, Kim Ah-hyun, and Korean American Jonathan Victor Lee were among those detained while attempting to deliver aid despite government travel bans. The activists later made graphic allegations of abuse during their detention, which Israel has denied.Huanqiu+2
