'Our world has been turned upside down' - Derry parent

More than 200 pupils at Nazareth House Primary School in Derry remain at home, after safety concerns over the school's roof forced it to close temporarily. We speak to a mother whose two children attend the school and the chair of the Catholic Council for Maintained Schools, Bishop Donal McKeown.
Also, we hear from Strabane GP Dr Ciaran Mullan about the extreme pressures health practices are facing across Northern Ireland.
And the quay at Lisahally where German u-boats berthed in 1945 has been designated a historical monument. We speak to Bert Whoriskey who watched some of the Nazi crews surrender to the Allies as a teenager.
