Jan 28 - Yemen is 'dismayed' by US President Donald Trump's decision to temporarily ban its citizens from traveling to the United States, saying that the country was a victim of attacks itself, an official said on Saturday. 'We are dismayed by the decision to unilaterally ban, even for only a month, travel to the United States for people holding Yemeni passports,' said the official, speaking on condition of anonymity. Yemen is one of seven Muslim-majority countries affected by Trump's 90-day curb on travelers while his administration studies new ways to prevent potential militants from trying to enter the United States.
