Israeli Prime Minister Benjamin Netanyahu on Sunday vowed to achieve victory and said his country's military "completely transformed reality" in the year since Hamas's October 7 attack, which has left the country fighting two wars.

Netanyahu told troops Israel "will win" as it battles militants in both the Gaza Strip and Lebanon and prepares to strike Iran, almost a year since the unprecedented attack by Palestinian Hamas militants sparked the Gaza war.

AFP correspondents heard explosions in south Beirut and its outskirts for more than two hours following the NNA's statement.

"France is not delivering any," he added during the interview, which was recorded Tuesday.

"For every action, there will be a proportional and similar reaction from Iran, and even stronger," he said.
