290 people are now known to have died following terror attacks in Sri Lanka after eight explosions hit churches and hotels yesterday.

As yet, no group has said it was behind the attacks, but 24 people have been arrested by authorities.

A nationwide curfew imposed shortly after the blasts, was lifted this morning.

Holidaymakers in Sri Lanka are being advised to stay indoors where possible and avoid large gatherings following yesterday's explosions.

The airport is still operating but security has been increased and some airlines are advising travellers to arrive early for check-in to allow extra time for screening.

On this holy weekend for many faiths, we must stand united against hatred and violence. I'm praying for everyone affected by today's horrific attacks on Easter worshippers and travelers in Sri Lanka.

The billionaire owner of Asos lost three of his four children in the terror attacks.

A spokesman for Anders Holch Povlsen - who is Denmark's wealthiest man - confirmed the news but didn't give any more details.

The US State Department says terrorist groups are continuing to plot attacks in the country, and it's claimed another assault could happen with "little or no warning."

President Michael D Higgins condemned the attacks:

"As President of Ireland I am sure that people in Ireland will have heard with great concern of the heavy loss of life that has happened at places of worship in Sri Lanka, at a time of religious significance."

"The right to the freedom of worship is a fundamental right."

"To the families of those who died and those who have been injured I send the sympathies and solidarity of the people of Ireland."

Sri Lankan Prime Minister Ranil Wickremesinghe said: "I strongly condemn the cowardly attacks on our people today.

"I call upon all Sri Lankans during this tragic time to remain united and strong."
