Iran said on Saturday that the resignation of Lebanese Prime Minister Saad Hariri would create tension in Lebanon and the region.
Hazem al-Amin, a Lebanese writer who follows regional affairs, said Hariri's resignation is "completely a Saudi step" that comes in the context of an worldwide and regional atmosphere against Hezbollah and against Iranian influence in the region.
Its warning came a day after Lebanese Prime Minister Saad Hariri announced his resignation. He urged Lebanese citizens not to hold protests in response to the resignation, saying "this will not lead to any result".
Lebanese President Michel Aoun will not accept Hariri's resignation until he returns to Lebanon to explain his reasons, palace sources said on Sunday, delaying for now the politically hard consultations over his successor.
He delivered it in a televised address from Saudi Arabia, leading his supporters and detractors in Lebanon to speculate he received orders to step down from Saudi Arabia, widely seen as his patron.
Hariri previously served as Lebanon's prime minister from 2009 through 2011.
Saudi Arabia's Crown Prince Mohammed bin Salman has tightened his grip on power through an anti-corruption purge by arresting royals, ministers and investors including billionaire Alwaleed bin Talal, one of the kingdom's most prominent businessmen.

His father, Rafik al-Hariri, was prime minister after Lebanon's 1975-1990 civil war and was assassinated in a auto bombing in 2005.
Saudi media have published reports of a plot to assassinate Mr Hariri in recent days, but all of Lebanon's main security branches have said they have no information about such a plot.
Al-Hariri placed the blame squarely on Iran and Hezbollah.
Lebanon has mostly managed to wall itself off from Syria's strife, with a flourishing tourism industry, as NPR's Ruth Sherlock reported recently.
Having Lebanon plunged in chaos and instability can only exacerbate an already messy regional scene.
A UN-backed tribunal has indicted five Hezbollah members for the killing but the group denies any involvement. Arab news sources said that al-Hariri had very recently survived an assassination attempt, which was the direct impetus for his decision.
Ghasemi dismissed Hariri's "baseless accusations", which he said indicate that "a new scenario" for the region was being drawn.
