USA officials say they're committed to a "stable, secure" Lebanon, while the European Union reaffirmed their support for the nation's sovereignty.
However, in a dramatic turn, the Saudi-led coalition claimed the missile was an act of aggression by Iran, who reportedly smuggled weapons to the Yemeni militias, according to Zero Hedge.
Consequently, during his three-hour flight to Riyadh, Hariri might have realized that he got more than he had bargained for when he took Aoun as an ally, and more importantly, that the entire year spent avoiding thorny issues and underscoring national unity was a farce exploited by Iran to its advantage. Saad Hariri, who resigned Saturday as Prime Minister of Lebanon, clearly depicts the latest tensions between Saudi Arabia and Iran.
"Hariri's resignation proves wrong the argument that Hezbollah participation in the government stabilizes Lebanon", the cable added.
Haley said the missile was not present in Yemen before the civil war.
According to the source, Iran's new stance stems, among other things, from its desire to recruit regional players in case of a confrontation between Israel and Hezbollah and the Iranian regime's ongoing campaign for regional hegemony.
This is not the first time Saudi Arabia has asked its citizens to leave Lebanon, but in the past has stated that the travel warnings were for the safety of their citizens.
On Thursday, two top Lebanese government officials accused Riyadh of holding Hariri captive.
The long-range ballistic missile was sacked by Houthi rebels in Yemen and intercepted by a major airport near Riyadh.
"Hariri's resignation signifies Iran's massive influence on Lebanon", he told Xinhua.
Earlier on Thursday Saudi Arabia also ordered its citizens to leave Lebanon days and the Gulf nation of Bahrain did the same earlier in the week.
Iranian President Hassan Rouhani on Wednesday touted "friendship" between Iran and Saudi Arabia, urging the kingdom to cease what he called their "hostile" policies towards the Islamic republic.
Hence, the source preferred anonymity to offer his views on the situation generated from the resignation of Prime Minister Saad Hariri.
"There are still a lot of chances to put things back on track in Lebanon", Zeid said.
