An Israeli military commander told an Israeli lawmaker on Tuesday that he would consider stepping down, as the Israeli military is struggling to find new ways to counter Iran’s military buildup in the Middle East.
The move would send a clear message to Tehran, and could lead to a wider reshuffle of the Israeli defense establishment.
Israel’s Chief of Staff Benny Gantz said he would resign at the end of March.
Gantz was speaking in response to a parliamentary question about a recent report by Israel’s intelligence services that said Tehran was building a network of tunnels in Syria.
The IDF has been conducting a series of airstrikes against suspected Iranian-backed Hezbollah targets in Syria since June, but the government says the strikes have been mostly limited to short-term anti-tank weapons.
The army has also targeted Hezbollah in Syria, which has been fighting to oust Syrian President Bashar Assad.
The government has long denied the accusations, which have been backed by the US.
The Israeli military has been under intense pressure to respond to the reports of Iranian support for the group.
The army has not conducted airstrikes against the group since May, but Israel is already engaged in a major offensive against the Shiite group in Syria and is considering another such campaign.
Last month, Israeli Prime Minister Benjamin Netanyahu said that he was considering resigning at the beginning of the year, and said the army would be reformed.
