A large chunk of the building has been damaged in the attacks, with its facade severely damaged and some of its interior windows shattered.

The roof has also been damaged and the water tower has been badly damaged.

The building also sustained a series of minor fires and power outages, which could be attributed to an electrical problem.

A local businessman who lives nearby told RTÉ News that a lot of damage was caused to the roof of the former residence of the late Taoiseach Bertie Ahern.

The damage was so severe that it could not be repaired.

“We are still in the process of rebuilding the building,” he said.

Koi is a symbol of Ireland’s republican past.

A number of members of the Royal family are said to have lived there at one time or another, including King William III.

The former residence has been demolished in recent years.
