Two Irish students have won bronze medals at the International Mathematical Olympiad (IMO).

Cillian Doherty, a sixth year student at Coláiste Eoin in Booterstown in Dublin, and Anna Mustata, a fifth year at Bishopstown Community School in Cork, picked up the prizes at the competition in Rio de Janeiro, Brazil.

It is the first time Ireland has won two medals at an IMO since first competing in 1988.

Ireland's team score was also the highest score ever achieved by an Irish team in the competition.

The four other members of the Irish team received honourable mentions.

112 countries competed in this year's contest, which is the World Championship Mathematics Competition for secondary-school students.

Each year the event is held in a different country, with the first IMO held in 1959 in Romania.
