The United Nations has urgently called for calm and respect for the ceasefire as Israel escalates its military offensive into Lebanon, jeopardizing US-Iran peace talks. Israeli strikes on southern Beirut and Hezbollah's rocket attacks on northern Israel have intensified tensions. Iran's Revolutionary Guards threaten to open new fronts in response to Israel's actions. The conflict has led to significant damage in Lebanon, including an airstrike on a hospital in Tyre, resulting in casualties. Both Israel and Hezbollah blame each other for the escalation, complicating diplomatic efforts.
