Hallgrimsson added that the second game against Israel on Sunday will go ahead as planned.

Speaking before tonight's game, Hallgrimsson said that he is not aware of a squad meeting to decide whether to play the game.

"The FAI (Football Association of Ireland) has said we are playing both games. That was our intention when we came into the camp and it is still our intention," said Hallgrimsson.

"We are trying to focus on the football. It is already decided we will fulfil the games."

The Republic of Ireland's most recent home game - a friendly against Qatar in May - was interrupted when fans threw tennis balls featuring the Palestine flag on to the pitch.

When asked about potential protests during tonight's encounter with Austria, Hallgrimsson said: "I must focus on football. I will let others think about security and those things.

"We are playing Austria, the highest-ranked team in the group. I'm not going to allow outside noise to affect me focusing on football."

The Football Association of Ireland is investigating whether forward Adam Idah was racially abused by Israel supporters during Sunday's 3-0 Uefa Nations League victory for the Republic of Ireland.

BBC Sport understands that midfielder Jayson Molumby spoke to the match officials during play, asking them to listen out for what he believed to be abusive chanting coming from some of the small number of Israel fans present at the match.

After full-time the officials informed FAI staff members that they did not subsequently hear any racist chanting.

When the FAI spoke to the Uefa match delegate about the alleged incident, they were informed that because no clear allegation of racism was reported during the game, the normal protocols had not been followed and a Uefa investigation could not take place.

The FAI is now conducting its own investigation by amassing high-quality footage of the match, including audio from pitchside microphones, in order to establish whether or not abuse was directed at Idah.

A panel is being set up by the FAI to analyse the footage and audio recordings. If the panel believes there is evidence to suggest Idah was abused, it will make a complaint to Uefa and request a further investigation by European football's governing body.

Idah was unaware of any possible abuse during the match and is now being supported by team-mates and staff members before the Republic of Ireland's remaining three fixtures in the current international break.

It is unclear whether the FAI would present its case to Uefa before or after Sunday's behind-closed-doors game against Israel in Backa Topola, Serbia.

BBC Sport has contacted Uefa for comment.

Republic of Ireland head coach Heimir Hallgrimsson said his players "raised awareness worldwide" after they chose not to engage in pre-match formalities with Israel.

The Republic of Ireland and Israel players did not shake hands and the Irish squad bowed their heads when Israel's anthem was played before their 3-0 win in Hungary.

There was also no exchange of pennants between Republic of Ireland captain Dara O'Shea and Israel skipper Manor Solomon, who did not shake hands.

"It has been so difficult for so many players," Hallgrimsson told broadcaster RTE after the game.

"I hope that will not be in the next game because they have shown support to the protest, they have raised awareness worldwide, not only in Ireland, on the subject and that is normally the reason for protesting, to raise awareness of a situation.

"I think these players have done that with all their actions, with all that they have been saying. No more than Gavin Bazunu, but the others have done it here on the pitch and how they have shown their actions, so I hope people understand that."

Three first-half goals saw the Republic of Ireland claim the first win of their Nations League Group B3 campaign against Israel in Hungary on Sunday.

Three days on from a disappointing defeat in Kosovo, the Irish enjoyed a much better showing in Debrecen as first-half goals from Troy Parrott, Adam Idah and Jack Moylan had them clear.

Israel pushed for a way back early in the second period but could not get past Caoimhin Kelleher, with the Irish in control for the most part to ease home.

As expected, there were no handshakes prior to the game, with the Republic of Ireland players bowing their heads during the Israeli anthem.

Despite the fraught build-up, Heimir Hallgrimsson's side began with confidence and were rewarded on 14 minutes as Parrott netted his 12th international goal when turning home James Abankwah's cutback.

The lead was doubled two minutes later and this time it was Idah who was put through by Moylan before slotting past Daniel Peretz into the corner of the net.

Kelleher was called into action to thwart Anan Khalaili, but the Irish went three goals clear in the 25th minute when Moylan drove into the box and fired home his first competitive international goal.

Hello and welcome to our live text commentary of Republic of Ireland's third Nations League B3 game against Austria at the Aviva Stadium in Dublin.

It is Heimir Hallgrimsson's side first game at home since a friendly win over Qatar back in April.

That game was twice briefly disrupted by fans protesting against the Nations League fixtures with Israel and further protests are expected tonight in this game that is sandwiched between the two behind-closed-doors encounters with Israel.

After a tumultuous time off the pitch during this international window, on the pitch, the Irish side will look to build on an encouraging 3-0 win against Israel on Sunday against the group leaders Austria, who have won their opening two games.
