One Israeli Defense Forces (IDF) division entered Gaza City between 7:03 PM and 7:17 PM UTC on September 15th, 2025, according to a Telegram post from a news outlet. This development occurs as regional tensions remain high. U.S. Secretary of State Marco Rubio stated earlier on September 15th that Hamas are "agents of terror and barbarism." A Trump administration official also denied claims that President Trump was warned of a planned Israeli operation targeting Hamas leaders in Qatar, calling such accusations "false." Intense air attacks, described as "fire belts," were conducted by the IDF in the western part of Gaza City on the eve of a second ground maneuver against Hamas. Security sources reported "intensity and significant" air attacks in Gaza City during the previous reporting period, contributing to the heightened regional tensions.
