Bahrain's foreign ministry ordered all Bahrainis to leave Lebanon ``due to the tense situation there, which requires caution,'' days after the United Arab Emirates did the same.

The ministry also warned its citizens not to travel to Lebanon ``permanently . in order to prevent exposure to any risks.''

Saudi Arabia, Bahrain, the UAE and Kuwait have all withdrawn their ambassadors from Beirut over televised remarks critical of the war in Yemen made by Lebanon's game show host-turned-information minister.

The comments by the minister, George Kordahi, ricocheted around the internet over the past week, infuriating the Gulf Arab region and triggering a series of punitive steps that further isolate Lebanon and threaten to split its new coalition government, now tasked with halting the country's economic tailspin.

The Yemeni civil war began in 2014 when the Houthis seized the capital Sanaa, 120 kilometres west of Marib, prompting Saudi-led forces to intervene to prop up the government the following year.

Along with pulling out their envoys, the four wealthy sheikhdoms expelled Lebanon's ambassadors from their countries. Saudi Arabia also banned all Lebanese imports, a major blow to the tiny country in desperate need of foreign currency.
