Bombs hit Georgia-South Ossetia conflict zone
A bomb exploded metres away from a moving column of Georgian military vehicles. It's believed that the bomb was detonated by remote control.
Earlier, a school was damaged in a separate blast, although no one was injured.
The third incident happened near the village of Nikozi, where a mine went off, injuring one person.
Georgian and South Ossetian authorities have called the incidents a 'provocation.'
Russian, Georgian and South Ossetian peacekeepers have patrolled the unofficial border since the ceasefire, following armed conflict over the breakaway republic's declaration of independence.
