U.S. envoy Tom Barrack’s visit to Lebanon opened the “window of diplomacy,” after a tense atmosphere that preceded his arrival in Beirut to receive the official Lebanese response to a three-point U.S. paper that most importantly contained a path leading to Hezbollah’s disarmament, a media report said.

Hezbollah has entered a state of maximum alert on its various military fronts in anticipation of a possible Israeli strike in the coming hours or days, unnamed sources told Al-Arabiya’s Al-Hadath channel.

Lebanese Forces leader Samir Geagea and his wife MP Sethrida Geagea hosted visiting U.S. envoy Tom Barrack in Maarab for talks that were followed by a dinner meeting overnight Monday.

The Israeli army said Tuesday that its two drone strikes in south Lebanon a day earlier had killed “a commander in the Radwan Force and another Hezbollah … operative.”

President Joseph Aoun handed U.S. envoy Tom Barrack "Lebanese ideas for a comprehensive solution" regarding Hezbollah’s arms during their meeting Monday at the Baabda Palace, the Presidency said, referring to Lebanon's official response to the U.S. paper submitted by Barrack on his earlier visit.

U.S. envoy Thomas Barrack said Monday he was satisfied by the Lebanese authorities' response to a request to disarm Hezbollah, which was heavily weakened in a recent war with Israel.

"I'm unbelievably satisfied with the response," Barrack, Washington's ambassador to Turkey and special envoy to Syria, told a press conference after meeting President Joseph Aoun in Baabda.

The Israeli army launched a series of airstrikes on southern and eastern Lebanon on Sunday evening, including in the area around the eastern city of Baalbek and in Iqlim al-Tuffah, a mountainous region overlooking large parts of southern Lebanon.

Hezbollah chief Sheikh Naim Qassem said in speech broadcast Sunday to mark Ashoura’s last day that his group will “continue the resistance” and “will not be part of legitimizing occupation in Lebanon.”

British Foreign Secretary David Lammy has visited Lebanon as part of a regional tour, reiterating the UK's "ongoing support for Lebanon's security, stability and future prosperity," the British embassy said.

The Foreign Secretary met with President Joseph Aoun at the Presidential Palace and discussions focused on the latest local and regional developments and UK-Lebanon bilateral relations.

U.S. envoy Tom Barrack on Saturday called on Lebanese leaders to seize what he called a "historic moment" to achieve reforms and the disarmament of armed groups, days before his second visit to the country to receive Lebanon's response to a U.S.-proposed paper.
