Taoiseach Micheál Martin has announced new public health measures to curb the spread of coronavirus in Dublin, which is continuing to see a rapid rise in infections.
The capital will now move into Level 3 of the Government's Covid-19 plan from midnight tonight for three weeks. Level 3 restrictions mean Dublin will be subject to tighter rules than the rest of the country.
Mr Martin said across Europe coronavirus is gaining a foothold and spreading at a rate not seen since March and April.
He said many countries have seen a "doubling of new cases" in the past two weeks.
Mr Martin said the threat of Covid-19 is growing in Ireland.
He added the capital is in a very dangerous place and that without action there is a real threat that Dublin could return to worst days of the crisis.
The measures include a ban on social or family gatherings indoors or outdoors and additional restrictions on indoor dining. No matches or events will be allowed and no spectators will be permitted at any games that take place.
For gatherings in a home or garden, visitors from one other household or your own household only are permitted. In other settings, no social or family gatherings should take place.
For weddings, up to 25 guests can attend a ceremony and reception. Religious services must move online with places of worship remaining open for private prayer. Funerals can be attended by up to 25 mourners.
Those living in Dublin are not allowed to travel outside the county except for work, education and other essential business.
Similarly, people outside the capital are advised not to travel into Dublin, with the same exceptions.
