Latvia has declared a state of emergency at its Belarus border, authorising border guards, armed forces and police to use physical force to return migrants to the country from which they came. Latvia, like neighbouring Lithuania, has faced an influx of mostly Iraqi migrants in the past few months from Belarus. Their borders are also the EU's external border. The state of emergency will run until 10 November and will enable the armed forces and the state police to assist the border guards. Lithuania is also erecting a four-metre metal fence topped with razor wire on its Belarus border, saying it is impossible to protect their borders. Tensions have been strained between Belarus and European nations since a disputed election last year returned President Alexander Lukashenko to power despite mass protests against his regime.
