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.

Israeli forces were targeting "terrorist infrastructure" in southern Gaza, the military said Friday, after Prime Minister Benjamin Netanyahu voiced hope that an agreement with Hamas could be reached within days for a pause in the 21-month war.

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