"Terrorists are very likely to try to carry out attacks in Bangladesh. The threat extends across the country," said the advisory on the U.K. Government's website.
"There's also the risk that foreign nationals could be directly targeted in future attacks; you should consider your movements carefully and follow any specific advice of the local security authorities," the advisory added.
Up to 150,000 British nationals visit Bangladesh every year.
Mentioning the last terrorist attack, targeting security forces, occurred in March 2017, the travel advisory warns of a risk that future attacks could target public gatherings.
An explosion took place on Monday in an underground tunnel linking the Port Authority Bus Terminal to Times Square in New York.
The 27-year-old Ullah was carrying a suspected pipe bomb that malfunctioned and exploded prematurely, leaving him and three others injured in the blast.
The New York City Police Department said that Ullah has been charged with- criminal possession of a weapon, support act of terrorism, and making terroristic threat.
He reportedly told investigators that the recent Israeli actions in Gaza, which were consequences of U.S. President Donald Trump declaring Jerusalem as the capital of Israel, compelled him to carry out the attack in New York, and that he was avenging attacks on the Islamic State (IS) group in the Middle East.
However, there is no evidence that Akayed, who is an electrician, had any direct contact with the IS.
The Bangladesh Embassy in Washington DC condemned the New York City terror attack and assured that Bangladesh Government was committed to its declared policy of 'Zero Tolerance' against terrorism. (ANI)
