Most of the Irish citizens who were held by Israel after it intercepted the Global Sumud Flotilla have now arrived home.
Five more out of a total of 15 will be back in Ireland later tonight.
Dozens of people including family members, friends and supporters gathered at arrivals to welcome home the pro-Palestinian activists.
Tadhg Hickey, Maureen Almaj, Diarmuid Mac Dubhghlais, Patrick O'Donovan and Paddy Kelly arrived at Terminal 2 this afternoon.
Both Mr Mac Dubhghlais and Mr O'Donovan said they were badly treated with no fresh water to drink while they were held in Ktzi'ot Prison.
A further five people landed in Dublin Airport after midnight, including Sinn Féin Senator Chris Andrews.
The first three Irish citizens arrived home last night and also said they were badly treated during their detention.
Speaking after arriving back to Dublin Airport this afternoon, the Irish citizens described aggressive behaviour from the IDF, a disregard for medical support and a lack of basic sanitary facilities.
Tadhg Hickey, a comedian who has two small children, including a baby just a few months old, said the treatment of those who were on the Flotilla was "inhumane".
He said there were 'SWAT' teams who would appear at the cells with dogs which he said "were brought into the room to intimidate us, guns put in our faces constantly".
Mr Hickey said he was surprised at the level of ill treatment they got: "I didn't think that white people, people of privilege, people with my type of passport would be subjected to that treatment."
He said he knew "they're utterly sadistic towards Palestinians" and challenged the Irish Government over its "diplomatic relations with a state that would kidnap humanitarians in international water and bring them to a torture camp for a week".
He said how one of the group was refused his insulin despite needing it as a medical necessity.
When asked whether Hamas had a role to play in helping to bring about peace, he said it was not his place to answer that: "I've no answer for such an irrelevant question. I mean, I don't know, like I'm just trying to bring baby formula to a besieged population. I really have no answer to that question."
He said it would be "inappropriate for me to tell any Palestinian faction during their own genocide what they should or should not do".
Another of the activists who landed on a flight from Athens, spoke about the mistreatment he received at the hands of the IDF.
Patrick O'Donovan said the IDF were very aggressive and violent when they were first arrested on their boats: "And then we were brought ashore and we were tied with tie wraps behind our back, our arms, behind our back at the port, and we were left there for about six hours on the ground."
He said after they were brought to the prison, the IDF "left us inside the cages. And then they were pointing guns into the cells at night-time".
Mr O’Donovan said he was delighted to see his family again "because I honestly didn't think I'd see them".
He said he hoped the Flotilla has heightened the awareness of what the Palestinian people need and the brutality of their circumstances there.
"We were hoping to get the aid through to them … but there's another flotilla on the way."
A further five activists including Sinn Féin Senator Chris Andrews will be arriving after midnight on a flight from Athens.

They were given a change of clothes, rehydration packs, water and essential medications when they arrived.

Another man, Michael Fix, the 16th Irish flotilla delegation member, holds a US passport and is part of a separate deportation process.
Ms Clancy, who is from Galway, described the last few days as "overwhelming" and "really unpleasant", adding that "however unpleasant they've been for us in an Israeli high-security prison, with all the world's media eyes on us, we can only imagine what it must be like for Palestinians".
She said the way the activists were treated once they were brought to Ashdod Port was a part of an Israeli media "spectacle" to show "this is how we will treat the people who arrive here".
Ms Clancy said the activists were transported to a prison "where we had no clean drinking water in our cell" and where people had to sleep on the floor.
"We continued to have no clean drinking water, no toilet paper, no sanitary towels for the women", adding that people did not have mattresses to sleep on and were being woken up throughout the night "for no reason".
Mr McClune said that after Israeli forces boarded their vessel "they tried to get us to write on legal documents that we tried to enter Israel illegally, which wasn't the case".
He said that when the flotilla activists were brought to Ashdod Port "they [Israeli soldiers] grabbed us by the arm behind our back, our heads down, and they put us in like a Guantanamo Bay sort of seating arrangement with our legs crossed, our heads down on the burning hot concrete."
Mr McClune said he would take part in the next mission, adding: "The more they try to dehumanise us, the more they dehumanise themselves, and the more resolute I am in going back and doing it again. Yeah, They're not going to stop me."
Niamh MacNamara, coordinator with Global Movement to Gaza Éire, said the Irish Government's "inaction" had "directly led to this situation, ordinary Irish citizens forced to risk their lives because leaders refused to act".
She added: "What happened was completely illegal under international law and should never have been allowed.
"If Ireland had imposed sanctions on the genocidal state of Israel and upheld human rights, this mission would never have been necessary.
"We demand immediate political action to protect those still sailing to Gaza and to end our complicity in this genocide."
Israel, which rejects accusations it is carrying out genocide in Gaza and says reports of hunger there are exaggerated, has dismissed the flotilla as a publicity stunt benefitting Hamas.
Talks to continue in Egypt on Trump plan to end Gaza war
Meanwhile, delegations from Israel and Hamas will continue indirect negotiations in Egypt that the US hopes will bring a halt to the war in Gaza.
Israel and Hamas have both endorsed the overall principles behind US President Donald Trump's plan, under which fighting would cease, hostages go free and aid pour into Gaza.
The plan also has the backing of Arab and Western states.
Mr Trump has called for negotiations to take place swiftly towards a final deal, in what Washington hails as the closest the sides have yet come to ending the two-year-old conflict.
Mr Trump, who has cast himself as the only world leader capable of achieving peace in Gaza, has invested significant political capital in efforts to end the war that has killed tens of thousands and left US ally Israel increasingly isolated on the world stage.
"I really think we're going to have a deal," Mr Trump told reporters at the White House last night as the delegations met in Egypt.
"We have a really good chance of making a deal, and it'll be a lasting deal," he added.
