Protesters have thrown masonry, flares, glass bottles and wooden planks at members of An Garda Síochána near a Dublin hotel for the second consecutive night.
Gardaí are attempting to disperse the crowd from the area outside the Citywest Hotel in Saggart.
A mounted garda unit and a dog unit are at the scene, along with the public order unit and a helicopter providing air support.
Stones and fireworks have also been thrown at gardaí. Hundreds of protesters gathered near the entrance of the hotel which is used to house asylum seekers.

It is the secondnight of demonstrations at the hotel following an alleged sexual assault on a 10-year-old girl in the vicinity of the hotel in the early hours of Monday morning.
Earlier, Garda Commissioner Justin Kelly said there will be a “robust response” to any continued disorder following a night of violence on Tuesday..
Mr Kelly said a further gathering outside the hotel had been proposed on social media.
A number of public transport services to the area have been suspended again including the Luas red line between Belgard and Saggart and the number 69 Dublin Bus.
Police were attacked with missiles and fireworks after violence flared outside the hotel on Tuesday night. A Garda vehicle was also set on fire during the unrest.
A woman Garda member injured during the violence has since been discharged from hospital.
Mr Kelly, who visited the scene earlier on Wednesday in the aftermath of the initial violence, told reporters on Wednesday he is “determined” that further people will be “brought before the courts to face justice”.

He said the disorder on Tuesday night was not a peaceful protest.
“I can promise that we will have a robust response again to any further disorder.”
Nearly 300 members of An Garda Síochána were on duty in response to the disorder.
This included more than 125 uniformed gardaí, 150 members of the public order unit and a water cannon, which was not ultimately used. Mounted and dog units also attended, supported by members in the air support unit.
A senior investigating officer has been appointed to probe the incident.

On Wednesday morning, shattered glass, a torn-down public bin and piles of bricks lay strewn across Garter Lane outside the centre.
A few metres away, the Garda van set alight by a mob the night before was being removed by a tow truck.
The disorder on Tuesday night involved up to 1,000 people, with six arrested following the disturbances.
On Wednesday afternoon, Taoiseach Micheál Martin praised gardaí for their “bravery, courage and professionalism” in dealing with the riot in Citywest on Tuesday night.
Mr Martin said in the Dáil, gardaí “come from our community and are there to protect us all”. It “beggars belief” that people would “articulate such vile abuse” and “then attack them in a very serious way”, he said.
