No-deal Brexit threatens key Ireland border
Failure to reach Brexit deal could cause new territorial dispute between Northern Ireland and the Republic of Ireland.

Al Jazeera’s Neave Barker reports from Carlingford Lough on the border between the two countries, which could soon be subject to a new territorial dispute.
