UNB, Dhaka: The US government has said it believes the threat of terrorism remains “real and credible” and feared that terrorist attacks could occur against foreigners. “US citizens in Bangladesh are urged to maintain a high level of vigilance in light of recent terrorist attacks and to monitor local security developments,” said John Kirby, Spokesperson of the US Department of State, in a daily briefing in Washington, DC on Thursday. He said the State Department issued a travel warning for Bangladesh on July 6 alerting US citizens to the ongoing potential for extremist violence and recommending US citizens consider the risk of travel to Bangladesh. “This travel warning supersedes the travel alert that was issued back in February of this year,” said the spokesperson. The US Embassy in Dhaka has imposed restrictions on personnel movement, Kirby said, adding that “Again, and I want to stress that anybody planning travel to the region ought to go to there and check it out.” “We provide US citizens with as much information as possible so they can make well-informed decision before they go,” he added.
