"Systemic care failings" that posed a "serious risk to life" have led to the closure of a care home in Enniskillen, County Fermanagh.
The Regulation and Quality Improvement Authority (RQIA) took the decision after an unannounced inspection at Ashbrooke Care Home last Wednesday.
The home is operated by Runwood Homes.
It said staff had not been given the opportunity to "address any concerns" the RQIA had with Ashbrooke Care Home.
The RQIA said it was liaising with authorities to organise "appropriate alternative care arrangements" for residents at the home.
The regulator's chief executive Olive Macleod said the "urgent unannounced inspection" at Ashbrooke came after the RQIA received "safeguarding concerns" the previous day.
"During RQIA's inspection, we found systemic care failings and concerns in relation to the management of the home.
"The RQIA considered that there was a serious risk to the life, health and wellbeing of all those living at Ashbrooke Care Home
