Regional tensions have risen in recent weeks between Saudi Arabia and Iran over Lebanese Prime Minister Saad al-Hariri's surprise resignation and after an escalation in Yemen's conflict.
Saad al-Hariri, who resigned as Lebanon's prime minister this month while in Saudi Arabia, told President Michel Aoun in a phone call he would be in Lebanon on Wednesday for Independence Day celebrations, Aoun said on Twitter on Saturday.
Lebanese President Michel Aoun said earlier this week that Hariri, who abruptly announced his resignation while in Saudi Arabia on November 4, was being held hostage by Riyadh.
Adel al-Jubeir said Saudi Arabia was consulting its allies about what leverage to use against Lebanese militant group Hezbollah to end its dominance in the small Mediterranean nation and intervention in other countries.
Lebanese Foreign Minister Gebran Bassil said on Wednesday that Lebanon will continue taking steps in "a brotherly way" to resolve the issue of its prime minister, Saad al-Hariri, who resigned while in Saudi Arabia and has yet to return.
Lebanon's Saad al-Hariri can only prove he is free by returning home from Saudi Arabia where he went to announce his resignation as prime minister, Lebanon's foreign minister said on Tuesday.
French Prime Minister Edouard Philippe said Tuesday that Lebanon's Saad Hariri must be able to return home from Saudi Arabia to end uncertainty caused by his shock resignation as prime minister.
