THINGS WE LEARNED

#SHOOTING: It emerged today that the gunman who shot and killed 26 people, including 20 children in a school in Newtown Connecticut “forced his way” into the school. All of the victims have now been identified but Connecticut Police have yet to release any names, including the name of the shooter.

#KEAVENEY: Labour TD Colm Keaveney has said comments by some ministers and Labour party members about his vote against the government on the Social Welfare Bill are “cynical” attempts to distract from issues around the budget.

#INDUSTRIAL ACTION: Trade Union SIPTU confirmed today that its members are set to ballot for industrial action against Bus Éireann over pay cuts and changes to their conditions of employment.

#FLOODS: High tides and winds are expected to continue along the Dublin coast this weekend with the Coast Guard urging people to avoid exposed cliffs or harbour walls. Recent rainfall levels across the country have varied from 10mm to 35mm.

#HOAX CALL: The family of a nurse who was found dead after being the victim of a prank call by Australian DJs while the Duchess of Cambridge was in hospital paid tribute to her today. After a memorial mass in London, Jacintha Saldanha’s husband said she was “the light in my darkness”.

#EGYPT: Egyptians began voting today on a new constitution supported by the ruling Islamists but contested by a secular-leaning opposition. International watchdogs have expressed concerns at loopholes in the new law that could weaken human rights in the country.
