He told his club's official website www.nufc.co.uk: "I feel honoured to have represented the Republic of Ireland on 44 occasions and have thoroughly enjoyed my international career.

Dublin-born Carr, who joined Newcastle in a £2m switch from Tottenham, made his international debut against Sweden in 1999.

Republic caretaker manager Don Givens, in charge for Saturday's final European Championship Group D qualifier with Wales at the Millennium Stadium, was complimentary about the right-back.
