DUBAI: Citibank will close most of its UAE branches and financial centers until March 14 as a precaution, its website showed on Thursday, as banks in the region sent staff home in response to a deepening Middle East conflict. The US financial group’s measures are the latest sign of growing concern among banks after Iran threatened Gulf banking interests linked to the US and Israel. The Citi branch in the Mall of the Emirates in central Dubai is exempted from the closure, the bank said on its website, adding it plans to reopen all affected branches on March 16.
