WASHINGTON: The United States had no advance warning of an Israeli strike in Beirut and U.S. Defense Secretary Lloyd Austin spoke with his Israeli counterpart as the operation was ongoing, a Pentagon spokesperson said on Friday.

“The United States was not involved in this operation and wehad no advanced warning,” spokesperson Sabrina Singh toldreporters.

Singh declined to say what Israeli Defense Minister YoavGallant told Austin about the operation and whether it targetedHezbollah leader Hassan Nasrallah. The Pentagon also declined to speculate on whether the Hezbollah leader was still alive.

Austin and Gallant spoke as the Pentagon chief flew over the Atlantic after a visit to London.

Israeli airstrikes rock Beirut, target Hezbollah leader Hassan Nasrallah

Asked what Austin may have communicated to Gallant given theIsraeli strike’s potential impact on U.S. efforts to secure aceasefire between Israel and the Iran-backed Hezbollah inLebanon, Singh declined to offer specifics, but she said thedefense secretary is always frank in his conversations with hisIsraeli counterpart.

“Look at just the engagements that the secretary and Minister Gallant have had over the last two weeks, speaking regularly. I think if there was any type of fracture in trust, you wouldn’t see those type of levels of calls and engagements occurring frequently,” Singh said when asked if the lack of advance notification by Israel indicated a lack of trust.

The Israeli military said it had targeted Hezbollah’s central headquarters in Beirut’s southern suburbs on Friday in an attack that shook the Lebanese capital and sent thick clouds of smoke over the city.

The news outlet Axios cited an Israeli source as saying Nasrallah was the target of the strike and that the Israeli military was checking if he was hit.

A source close to Hezbollah told Reuters that Nasrallah was alive, while Iran’s Tasnim news agency also reported he was safe. A senior Iranian security official told Reuters that Tehran was checking his status.
