Ajman Bank has sacked its Chief Executive Mohammed Zaqout, less than six months after appointing him to lead the United Arab Emirates' lender. The Islamic bank said it had terminated the services of Zaqout with effect from Sunday, with Chief Financial Officer Seifeldin Abdelkareem becoming acting CEO. The bank, listed on the Dubai Financial Market since 2008, is 25-percent owned by the government of Ajman.
