Places of worship

Will gardaí arrest people?
Taoiseach Leo Varadkar said they hope to use new powers sparingly. The intention is that there will be a much stronger garda and park ranger presence and they will disperse groups and encourage people to move on.
Individuals can visit families and loved ones but should do so less frequently and in small groups.
Differences between North and South
The Taoiseach said there would be some differences, such as gatherings of four people in the Republic of Ireland versus two in Northern Ireland.
