Planes and helicopters have flown over the Romanian capital as thousands turned out to celebrate the national day, marking the date when the country reunified with Transylvania in 1918.

President Klaus Iohannis and Prime Minister Dacian Ciolos were among senior officials who watched a military parade Thursday.

Some politicians were absent after Iohannis said he would not invite to the celebrations those who are being investigated for wrongdoing

The normally busy capital of 3 million was almost deserted on a sunny but cold day. Soldiers paraded in military vehicles.

In a sign of tensions, Hungarian Foreign Minister Peter Szijjarto told Hungarian diplomats not to attend the celebrations.

Transylvania was formerly part of the Austro-Hungarian empire and 1.4 million ethnic Hungarians who mainly live in Transylvania are seeking greater autonomy.
