Lebanon's prime minister Saad al-Hariri gestures during a press conference in parliament building at downtown Beirut, Lebanon October 9, 2017.
In a televised address on Saturday, Prime Minister Hariri announced an unexpected resignation saying the atmosphere in the country resembles that before the assassination of his father, former Lebanese Prime Minister Rafic Hariri, who was killed in 2005.
There is "no danger to the economy or pound", Khalil said.
During his resignation, Hairi accused Iran and its Lebanese-based proxy Hezbollah of taking over Lebanon and destabilizing the region. "Iran very much wants to bring chaos and destruction to the Arab world, but the evil it is sowing will return to it and attack it like a boomerang", he said.
"Do not listen to alarmist speeches", Nasrallah said.
Assad and his Iranian-supported allies are now firmly in command of the war in Syria, in a humiliation to Saudi Arabia and the Gulf. Hariri became Lebanon's prime minister in 2016 in a deal that also brought in Hezbollah ally Michel Aoun as the country's president.
The government was formed late last year in a political deal that ended years of deadlock, and last month it produced Lebanon's first budget since 2005.
The Saudi-owned daily also said Hariri believed he was being used as a cover by Iran and Hezbollah to "lead the country towards great adventures where he will be a pawn to cover up their actions". Hariri is Lebanon's most influential Sunni politician.
A United Nations -backed tribunal has indicted five Hezbollah members for the killing but the group denies any involvement.
He added that Hariri resigned from Riyadh for security reasons.
A Saudi minister said on Saturday that Hariri's personal security detail had "confirmed information" about the plot.
