U.S. National Security Adviser Jake Sullivan, in Israel, announces a shift in the Gaza conflict strategy to target Hamas leadership with precise operations. Amid global pressure to reduce civilian casualties, the new phase aims for intelligence-driven missions. Sullivan hints at a multi-phase approach over months but remains vague on the timing. Discussions involve Israel's leaders on the war's evolution. He avoids detailing potential consequences like withholding military aid, emphasizing behind-the-scenes talks for progress.
