The Taoiseach has said that the Department of Transport is continuing to make "inquiries" in relation to a US plane carrying deportees which reportedly stopped at Shannon Airport this week.
It was reported in the New York Times that an aircraft with a number of people on board landed at the Co Clare airport on Tuesday night.
The newspaper said the flight landed in Shannon at around 9.39pm for around two hours, before continuing its journey to the African nation of Djibouti.
Speaking to reporters in Cork, Micheál Martin said "we need to be careful about a knee-jerk reaction to one individual flight, if that's the case".
However, he confirmed that Department of Transport officials are seeking answers over the flight.
The incident was raised by Labour leader Ivana Bacik in the Dáil yesterday.
"These are deportation flights which are illegal, taking place in violation of a US court order," she said.
"In other words, an Irish airport has been used as an instrument to violate human rights," she added.
When asked about the incident, the Taoiseach said that there are "various international and legal agreements pertaining to aircraft landing and re-fuelling" in other countries.
He said this means "it wouldn't have been immediately apparent there were deportees [from the US] on any flights", and that "further inquiries are being made by the Department of Transport".
Asked if all civilian flights now need to be reviewed or checked, the Taoiseach said: "I think we need to be careful about a knee-jerk reaction to one individual flight, if that's the case."
"We'll assess it [the situation], these are issues we will review and we will take a position on," he said.
