A series of protests against Brexit have taken place along the border between the Republic of Ireland and Northern Ireland.
The demonstrations have been organised by the campaign group Border Communities against Brexit.
Protesters say Northern Ireland should be allowed to stay in the EU because the majority of voters there voted remain.
Hundreds of people turned out at border crossings, with protestors gathering at Lifford Bridge on the Donegal-Tyrone border, Bridgend on the Donegal-Derry border, Carrickcarnon on the Louth-Armagh border, Moybridge between Tyrone and Monaghan Aghalane between Fermanagh and Cavan.
Those taking part handed out leaflets setting out their fears that pressing ahead with a divorce from Europe could lead to negative implications for those in the border regions.
There are genuine fears that border checkpoints could return in Ireland and a mock checkpoint and customs building was erected to press home this point.
But British prime minister Theresa May has already clearly set out her next move for Brexit.
She has given her clearest indication yet of the Brexit timetable, saying that article 50 would be invoked in March next year to start the process of officially leaving the EU.
Mrs May told delegates at the recent Tory party conference that she was more than prepared to carry out the wishes of the majority of Britains, who voted to Brexit.
She said Britain would be sacrificing the Single Market in order to be in control of its own destiny and to have more say in its own immigration policies.
The Prime Minister also said there would be no special relationship for either Northern Ireland or Scotland and the EU.
Setting out her stall, she said: “Because we voted in the referendum as one United Kingdom, we will negotiate as one United Kingdom, and we will leave the European Union as one United Kingdom.
“There is no opt-out from Brexit. And I will never allow divisive nationalists to undermine the precious union between the four nations of our United Kingdom.”
Meanwhile, the British diplomat who authored article 50 has urged Mrs May to allow the public to vote on the final terms of a Brexit. His comments come after the foreign secretary Boris Johnsonsaid that Britain should be able to have its cake and eat it when it comes to Brexit.
Lord Kerr of Kinlochard said: “Once the government, some way down this process, has established clearly what Brexit will be like, if it turns out that Boris’ policy on cake doesn’t work, then it might be not a bad idea to ask the country in a general election, or possibly another referendum, whether this is actually what it had in mind.”
