Post mortem examinations are being carried on the bodies of the seven family members killed in the Omagh house fire.
Arthur McElhill, Lorraine McGovern and their five children died in the fire in Lammy Crescent on Tuesday.
The national school next door to the house at the centre of Omagh's fire tragedy reopened this morning.
St Conor's School, where seven-year-old Sean Mc Elhill and his four-year-old sister Bellina attended, had been closed since Tuesday.
Their 13-year-old sister, Caroline, was a past pupil.
Councillors and psychologists were in the school this morning to help the parents and their children cope with the tragedy.
Last night, hundreds of people lined the street as the bodies were removed from the house.
The PSNI says it is investigating seven murders and has denied reports that their inquiry is concentrating on one main suspect.
A PSNI spokesman said that no one has been declared as a suspect at this stage and warned media outlets to be 'extremely careful' in reporting the case.
The house remains sealed off as the police continue to consider it a crime scene.
What the PSNI describes as a significant quantity of petrol was discovered inside the house.
An expert fire investigator from England was called in by the police in order to establish the origins of the blaze.
