A fire has broken out close to Dublin's Connolly Station leading to the closure of two platforms.
Firefighters are tackling the blaze at a derelict house in Dublin city centre amid fears that there may be someone sleeping rough inside.
The alarm was raised at around 5.15pm when smoke was seen streaming from the three storey terraced house on Preston Street, off Amien Street, in Dublin 1.
A plume of thick black smoke could be seen coming from the top floor as the fire quickly spread through the abandoned building.
Firefighters at the scene said they could not rule out the possibility that someone may still be inside the building.
"We just don't know yet. Homeless people have been known to use the place as somewhere to sleep," said one firefighter this evening.
Several crews are at the scene with the fire having started on the ground floor, according to a source.
A large number of onlookers stopped on the street and watched the fire service fight the blaze.
Firefighters at the scene said they were forced to use a specialist generator to get the pump working due to the recent shortage of water in the Dublin region.
They tackled the flames before staying on-site to clear the building and to ensure it would not be in danger of re-igniting.
Motorists were diverted away from the area and, given its proximity to Connolly Station, DART services have been curtailed.
“Trains are running but platforms six and seven at Connolly are closed because they’re quite close to that building,” Barry Kenny of Irish Rail told the Irish Independent.
“All DART and commuter trains, northbound and southbound, are going through platform five. There are delays of between fifteen and twenty minutes.”
A spokesperson from the Dublin Fire Brigade said that they could not be sure that there were no fatalities as a result of the fire.
“There have been no injuries at the minute but we can’t be sure until we have searched the entire building,” he said.
