The 120-kilometer-long Blue Line border between Israel and Lebanon

NABATIEH GOVERNORATE, LEBANON - AUGUST 26: The United Nations Interim Peace Forces (UNIFIL) stand guard holding the flag of the United Nations by the border at the Kafr Shuba region, considered a disputed area between Lebanon and Israel, to ensure security in the town of Kafr Shuba in Nabatieh Governorate, Lebanon on August 28, 2023. Following Israel's withdrawal in 2000 from southern Lebanon, which it seized in 1982, the UNIFIL took control of the 120-kilometer-long border referred to as the 'Blue Line'. Discussions on the extension of UNIFIL's mandate in Lebanon are ongoing with the Lebanese government. (Photo by Houssam Shbaro/Anadolu Agency via Getty Images)
