Saudi Arabia, the United Arab Emirates and Bahrain have urged their citizens to leave Lebanon or avoid travelling there. The UAE also banned its citizens from travelling to Lebanon and reduced its diplomatic presence in Beirut. Bahrain also urged citizens against travelling to Lebanon, and called on Bahrainis there already to leave quickly, according to a statement posted to state news. The move on Tuesday came after Riyadh halted $4bn in aid to Lebanese security forces in response to "hostile" positions linked to Lebanese Shia group Hezbollah. On Friday, the United Arab Emirates announced "full support" of Saudi's review of its relations with Lebanon, blaming the country's "failure to condemn Iran's aggression" after Saudi Arabia's embassy was attacked in Tehran in January.
