Watch again as the Omagh bombing public inquiry held its first hearing on Tuesday, 28 January.
Twenty-nine people, including a woman pregnant with twins, were killed in the attack carried out by the Real IRA in the Co Tyrone town in August 1998 in what was the biggest single atrocity of the Troubles.
A High Court judgment recommended a public inquiry into alleged security failings in the lead-up to the atrocity and also urged the Irish authorities to establish their own probe.
The Irish government formally agreed to assist with the inquiry.
Bereaved families and survivors gathered at the Strule Arts Centre in the Co Tyrone town.
The inquiry will hear commemorative and personal statements over the next four weeks.
Tuesday’s hearing commemorated those who were killed in the bombing and started to hear from people who were affected by the bombing.
There will be commemorations of Fernando Blasco Baselga, 12, and Rocio Abad Ramo, 23, two Spanish nationals killed in the attack.
