Nasrallah's televised speech came four days after the rare strike that some Syrian opposition activists claimed was carried out by Jordan's air force.

Saudi Ambassador to Lebanon Walid Bukhari has told the majority-Sunni National Moderation parliamentary bloc that “Saudi Arabia has no veto on anyone nor a veto on Suleiman Franjieh,” a media report said.

The opposition has tried to agree with Free Patriotic Movement chief Jebran Bassil on a presidential candidate who would enjoy the broadest support in parliament and who was his candidate in the first place, a media report said on Friday.

Saudi Crown Prince Mohammed bin Salman has said yes to French President Emmanuel Macron for Suleiman Franjieh, the French daily Le Monde quoted a French diplomat as saying.

Lebanese Forces leader Samir Geagea has reversed his stance on choosing a “confrontational candidate” and has accepted to endorse “a consensual candidate who wouldn’t provoke Hezbollah in particular,” a media report said.

A meeting between Saudi Ambassador Walid Bukhari and Hezbollah's presidential candidate Suleiman Franjieh, although dubbed by some local media as an ordinary meeting, was considered a "major positive Saudi shift" by a senior political source.

Thursday’s meeting in Yarze between Saudi Ambassador to Lebanon Walid Bukhari and Marada Movement chief Suleiman Franjieh “did not change the kingdom’s stance as to what it has declared regarding the Lebanese presidential juncture,” a media report said on Friday.

“What Franjieh heard from the ambassador was the same stance that the other parties heard from him: his country does not have any problem with anyone and it does not support or veto anyone,” Annahar newspaper reported.
