Caine held talks with Haykal on Tuesday and Qatar's defense chief the day before, "reaffirming the importance of the United States' enduring defense relationships in the Middle East," US Joint Staff spokesman Joseph Holstead said in a statement, without providing further details.

Haykal was scheduled to visit Washington in November 2025, but the trip was called off after US political and military officials canceled their meetings with him just hours before he was scheduled to depart, a military source told AFP at the time.

Those who canceled included influential Republican Senator Lindsey Graham, who at the time slammed what he said was Haykal's "almost non-existent effort to disarm Hezbollah."

On Thursday, Graham said on X he had abruptly cut their meeting short after asking Haykal whether the Lebanese military considered Hezbollah to be "a terrorist organization."

Graham said that Haykal replied, "No, not in the context of Lebanon."

The Lebanese military announced last month that it had completed the first phase of its plan to disarm the militant group, covering the area between the Israeli border and the Litani River.

Under a November 2024 truce that sought to end more than a year of hostilities, Iran-backed Hezbollah must withdraw its forces north of the Litani and have its military infrastructure dismantled in the evacuated areas, while Israeli forces must exit Lebanon.

But Hezbollah has rejected calls to surrender its weapons, and Israel has kept up regular strikes on Lebanon while maintaining troops in five areas near the border that it deems strategic.
