The IDF said Thursday it was sending additional troops to reinforce the northern border with Lebanon after the Hezbollah terror group threatened retaliation after one of its fighters was killed in Syria in an alleged Israeli air attack.

“In accordance with the situational assessment that was held in the IDF, it was decided to add pinpoint reinforcements of infantry troops to the Northern Command,” the IDF said in a tweet.

Israel decided to boost its forces on the confrontation line with Hezbollah after an attack earlier this week near Damascus International Airport killed five combatants including a fighter from the Iran-backed terror group that is fighting on behalf of Syrian dictator Bashar Al-Assad. The airstrike was widely attributed to Israel, AP reported.

The terror group has in the past retaliated for Israeli strikes that killed its fighters. Last September, after two of its fighters, were killed in an Israeli airstrike in Syria, Hezbollah fired two anti-tank missiles that struck IDF vehicles just inside the Lebanese border, but no Israelis were injured.

Last week, Gen. Kenneth McKenzie, Commander of U.S. Central Command (CENTCOM), said Hezbollah would be mistaken to try and take on Israel in a military conflict during a special briefing in Dubai.

“I think it would be a great mistake for Hezbollah to try to carry out operations against Israel. I can’t see that having a good ending,” McKenzie said.
