Saudi Arabia is urging its citizens to leave Lebanon or avoid travelling there after cutting $4 billion in aid to Lebanese security forces.

The Foreign Ministry's announcement was carried by the state-run Saudi Press Agency on Tuesday. It urged citizens to be in contact with the Saudi Embassy in Beirut.

The announcement gave no reason for the warning.

Saudi Arabia announced Friday that it was halting deals worth $4 billion aimed at equipping and supporting Lebanese security forces in retaliation for Lebanon siding with Iran in the Sunni kingdom's spat with the Shiite power.

Lebanon's main political divide pits a Sunni-led coalition against another led by the Iran-backed Shiite Hezbollah movement. Lebanon has seen a series of militant attacks in recent years linked to the conflict in neighboring Syria.
