Hezbollah said on Wednesday that it fired missiles at a military base near Ben Gurion Airport, Israel's main international gateway.
Israeli media reported on Wednesday that a rocket had landed near the airport. The airports authority said the airport was continuing to operate as usual.
Israeli forces and Hezbollah have been clashing for more than a year, since Hezbollah started firing rockets across the border soon after the deadly Hamas-led attack on southern Israel sparked the ongoing war in Gaza in October last year.
The war on the Lebanese front has substantially escalated since mid-September, with Israel launching a massive aerial bombardment and ground invasion.
