"The enemy wanted an open war, which he has not stopped since the ceasefire agreement decision, so let it be an open war," Qamati said in a statement, referring to the November 2024 ceasefire agreement between Israel and Hezbollah, since which Israel has continued to bomb Hezbollah targets in Lebanon and has maintained military positions in five locations in the south of the country.
