Two Thai soldiers have been hurt in grenade attacks.

The grenades were thrown onto a Bangkok military base from someone outside the compound.

The male soldiers, aged 23 and 49, where admitted to Bangkok's army-run King Mongkut hospital, where their condition was described as stable.

Military officials on the base said they thought the grenades had been shot from a car driving past.

At the time of the attack, thousands of people had been milling outside another army base across the city in a mass protest against the government.

Crowds of red-shirted protesters have been forming picket lines in front of the 11th infantry army barracks on Bangkok's northern outskirts, from where the government operates, to press their demand that current Prime Minister Abhisit Vejjajiva call snap polls.
