HERE ARE THE things you need to know as we round off the day in three easy steps.

THINGS WE LEARNED

#ATTACK: Two Irish men aged in their 30s are in critical but stable condition in hospital in Melbourne after being attacked by a man with a hammer at their accommodation overnight.

#PROPERTY TAX: Two ministers said today that the government has not yet decided how property tax could be calculated, while the Department of Finance said that the interdepartmental report on the issue is currently with Minister for the Environment Phil Hogan.

#THE LETTER: Minister Michael Noonan has said he favours publishing a letter written by then-ECB chief Jean-Claude Trichet to then-Finance Minister Brian Lenihan ahead of Ireland accepting the Troika’s bailout loan. Here’s what happened when we asked for a copy of that letter.

#SYRIA: Syrian opposition and pro-government fighters were this evening blaming each other for the massacre of dozens of Syrians after footage purporting to show the bodies was posted online.

#NEIL ARMSTRONG: Tributes have been pouring in for Neil Armstrong, the first man to walk on the moon. In this BBC interview filmed just months after his return, the Apollo 11 astronaut recounted his experiences on the moon mission.
