About 2,000 Moldovans and Romanians have called for their countries to be reunited, throwing flowers onto a river separating the two countries.

Moldovans gathered in the southern village of Ungheni on Saturday and shouted "Unification!" Romanians rallied on the other bank of the Prut river.

Some people crossed the border from both sides to demonstrate friendship.

Moldova, an ex-Soviet republic, was part of Romania between 1918 and 1940. They both speak Romanian.

Thousands have rallied in the Moldovan capital in recent months calling for reunification. Moldova signed an association agreement with the European Union last year, angering Russia.

Romania, already an EU member, is a strong supporter of Moldova's ambition to join the bloc.

The ceremony at the Prut river has been taking place annually for 20 years.
