Saudi King Salman bin Abdulaziz Al Saud received former Lebanese Prime Minister Saad Al Hariri in Riyadh on Monday following his resignation, Saudi media reported.
Hariri announced his resignation on Saturday from Riyadh, saying he believed there was an assassination plot against him and accusing Iran and its Lebanese ally Hezbollah of sowing strife in the Arab world.
"King Salman met the resigned Lebanese Prime Minister Saad Al Hariri a short while ago," a presenter on Al Arabiya television said.
Hariri's resignation toppled a coalition government that included Hezbollah.
State news agency SPA carried pictures of Hariri and King Salman greeting each other and then sitting together in a palace.
Lebanese Justice Minister Salim Jreissati said on Monday that Lebanon's president would not take any steps regarding Hariri's resignation before Hariri returns from abroad.
President Michel Aoun said earlier on Monday that political leaders had been responsive to calls for calm, strengthening security and national unity after Hariri's shock resignation.
