Firebombs have been thrown at police during an illegal dissident republican march in Londonderry.

Sections of the crowd pelted a PSNI Land Rover with missiles, including petrol bombs, as the Easter commemoration parade made its way through the Creggan area of the city on Monday.

Photographs showed masked youths throwing petrol filled bottles at the Land Rover before it managed to speed away.

The violence came amid a series of events across Northern Ireland to commemorate the signing 25-years-ago of the historic Good Friday Agreement which marked the end of ‘the troubles’.

Police in Northern Ireland had warned of the potential for dissident republicans attacking officers in Londonderry on Easter Monday.

Senior detectives said "strong" intelligence had indicated that public disorder could be used to launch attacks on officers in the city.

The heightened tension came a day before US President Joe Biden is to visit Belfast for the 25th anniversary of the US-brokered peace accord.

Further events will be held the following week, due to be attended by former US president Bill Clinton and his wife, former US secretary of state Hillary Clinton.
