U.S. says it would help Israel defend itself if attacked by Hezbollah

The U.S. will defend Israel in the event of an attack by Hezbollah, defense chief Lloyd Austin said Tuesday.

"If Israel is attacked, yes, we will help Israel defend itself. We've been clear about that from the very beginning," Austin told reporters in the Philippines.

Austin said he does not believe "a fight is inevitable," and the U.S. wants to see "things resolved in a diplomatic fashion."

The defense chief said the U.S. remains concerned about the potential for a conflict between Israel and Lebanon to escalate into a full fight.

His remarks came after an Israeli strike in the vicinity of Hezbollah Shura Council headquarters in Haret Hreik.

State-run National News Agency reported that the attack was carried out with an Israeli drone, which fired three missiles into a building in Beirut's southern suburb, destroying two floors.

The Israeli army confirmed the strike, claiming it targeted a Hezbollah commander responsible for Saturday's missile attack that killed 12 people in the town of Druze in Majdal Shams in Israel-occupied Golan Heights.

While Israel blamed Hezbollah for Saturday's attack, the Lebanese group denied any responsibility.

There was no immediate comment from Hezbollah on the attack.

Fears have grown about a full-blown war between Israel and Hezbollah amid an exchange of cross-border attacks between the two sides.

The escalation comes against the backdrop of a deadly Israeli onslaught on the Gaza Strip, which has killed more than 39,300 victims since October, following an attack by the Palestinian resistance group, Hamas.
