Motorists are being asked to avoid the Tullyah Road area of Belleeks in south Armagh after reports of a school bus having been involved in a collision.
Emergency services are at the scene of what is being described as a serious road incident between Newtownhamilton and Camlough, this afternoon (Tuesday).
There are reports of a school bus, carrying dozens of children, on its side.
A PSNI spokesperson said: “Please avoid the area and seek alternative routes.
“An update will be issued in due course.”

She added: “I understand an incident occurred earlier today involving a school bus travelling from St Paul’s on the Tullyah Road in the Whitecross area.
“I am relieved to hear that no children were hurt.
