1. Obama says Florida gunman a product of homegrown extremism

The gunman behind the worst mass shooting in US history was "cool and calm" as he talked to police during his bloody rampage that left 49 people dead and 53 injured, according to Florida police. Further details of the horrific attack on the gay nightclub Pulse in Orlando on Sunday morning emerged yesterday as law enforcement officials shed more light on why Omar Mateen (29), a US citizen of Afghan descent, might have carried out the massacre. As the almost three-hour hostage situation unfolded, Mateen spoke to police by telephone and said he was carrying out the attack for the leader of Islamic State, the Middle-Eastern militant extremists, and pledged allegiance to the radical group.

2. Green shirts take over ‘red light’ district

You would expect last year's Paris attacks to have had an effect on the way Irish football fans socialise in the streets of the French capital. Au contraire. If anything, their exuberance is even less restrained than it was in the innocent days of 2009, for example, when the only cause for concern was Thierry Henry cheating us out of a place in the World Cup. As on that and other occasions, the fans still tend to congregate at night around three Irish bars on the Boulevard de Clichy in Pigalle. The Moulin Rouge is adjacent and so are numerous sex shops, making this a kind of red light district. But that appears to be a mere coincidence. When the Republic of Ireland team is in town, the area becomes a green shirt district. And the only activities any of the shirt wearers seem to be interested in are drinking and having fun.

3. Leaving Cert diary: 'Exemption be damned. I really like Irish’

I blanked. It wasn't in the plan, of course, but I sat there looking at Irish paper 1, and I blanked. I came to Ireland from Hong Kong when I was 11, having previously lived here until I was two. They gave me the choice about whether or not to do Irish but, as a kid, I was always interested in learning and, as it turned out, I was good at the language. So, exemption be damned, I did it. I really like the Irish language and have never found it that hard to learn. I think it helps that I already speak Cantonese and a little Mandarin, so my mind seems to get the concepts of how other languages work.

4. €100m infrastructure fund for sites owned by developers

Local authorities are to be given a fund to build infrastructure servicing sites owned by developers under a new scheme to be announced by the Government today. The scheme would mean the cost of providing such infrastructure would be at least partially borne by the State and not the builder. It is part of wider Government efforts to make the cost of developing houses cheaper. http://www.irishtimes.com/news/politics/cabinet-to-announce-100m-infrastructure-fund-1.2683448Minister for Housing Simon Coveney had previously said the Government would help private developers to build homes by reducing their costs. This could be done by bringing down the cost of accessing finance for builders or reducing the costs associated with construction, such as access routes into estates. He also said, in such circumstances, it would be Government’s aim that most of those homes and apartments would be affordable or in the €250,000-€300,000 range in Dublin.

5. Should everyone be paid €752 a month

There's nothing new about the concept; as long ago as 1797 political activist Thomas Paine proposed it in his pamphlet Agrarian Justice". However in recent times there has been an increasing amount of rhetoric pushing the concept of a basic income, which is handed over by the State to all, no questions asked. So much so that on June 5th, Switzerland voted on whether or not to introduce such a system. What's behind the movement, though, and could the concept of paying every adult in Ireland €188 a week – regardless of their needs – actually work?
