Sinn Fein's Martin McGuinness has said people should not celebrate the death of Margaret Thatcher.
The former prime minister died yesterday aged 87 after suffering a stroke while staying at the Ritz hotel in central London.
"Street parties" were held in Derry, West Belfast and in other parts of the UK last night.
In a tweet, the Norths Deputy First Minister Martin McGuinness said people should "resist celebrating the death of Margaret Thatcher".
He also added that she was not a peacemaker but it is a mistake to allow her death to poison our minds.
The PSNI have said it's making inquiries after a disturbance in the area around Free Derry Corner at 7 o clock yesterday evening.
Petrol bombs were thrown at police. No damage was caused and there were no injuries.
