The Israeli Air Force conducted airstrikes on military infrastructure at Yemen's Hodeidah port and a Hezbollah headquarters in Nabatieh, southern Lebanon, on Monday night, September 16th, 2025. The IDF confirmed targeting the Hodeidah port piers and docks, used for transferring Iranian-supplied weapons, resulting in heavy damage and operational cessation. Separately, the IDF stated the Nabatieh strike targeted a Hezbollah headquarters, deeming its presence a violation of understandings between the two countries. Throughout the reporting window, the Israeli Air Force intercepted one missile launched from Yemen, with warnings activated in several Israeli localities including Shepheon, Shphelat, and areas in Judaea. The IDF stated that "The Air Force continues to operate in all arenas," and "The IDF continues to strike military targets in Yemen in response to the repeated attacks by the Houthi terrorist regime against Israel and its civilians." Earlier in the day, the IDF had confirmed concluding airstrikes on military infrastructure at Hodeidah port by 1:48 PM UTC, citing its use for weapon smuggling from Iran. This action followed IDF advisories urging immediate evacuation of the port and vessels, and an advisory from the UK Maritime Trade Operations (UKMTO). Hezbollah, meanwhile, is reportedly preparing for the first anniversary of an Israeli "biopper attack" against its people, with the slogan "We have recovered."
