From UNSC:
On 1 August, at about 8 a.m. Tbilisi time, a
pickup vehicle containing six Georgian police officers
was hit by two remote-control explosive devices. As a
result of that attack, five Georgian policemen were
severely wounded. The central authorities decided not
to retaliate, so as not to escalate the situation.
On 2 August, six civilians and one Georgian
policeman were injured during the overnight shelling
of seven Georgian villages in the South Ossetian
conflict zone. The seven Georgian-controlled villages
came under intense fire from South Ossetian separatists
using large-calibre mortars. Georgian law-enforcement
personnel fired back defensively for some time but
then received a ceasefire order aimed at not escalating
the situation.
Late on 6 August, separatists opened fire with
mortars on Georgian-populated villages: Eredvi and
four others. Georgian Government forces fired back to
defend the civilian population. As a result of intense
crossfire during the night, two servicemen belonging to
the Georgian battalion of the Joint Peacekeeping
Forces were injured.
Overnight and in the early-morning hours of
7 August, intensive fire came from four positions in
various Ossetian villages. The separatist authorities
continued firing on Georgian law-enforcement
personnel and peacekeeping units with mortars and
artillery. The central authorities responded with limited
fire in order to defend those positions.
You can find collaborating information in plenty of sources. This is anything but quiet.
