As Israel and Hamas move closer to a ceasefire agreement, Israel says it wants to maintain troops in a southern corridor of the Gaza Strip — a condition that could derail the talks.

The Gaza Humanitarian Foundation, a controversial U.S.-backed aid distribution initiative supported by Israel, is currently the primary method for Palestinians in devastated Gaza to access supplies in designated spots after Israel lifted its aid blockade in mid-May.

The Israeli delegation didn't have a sufficient mandate to reach an agreement with Hamas, two Palestinian sources told Reuters.
