The Georgian Ministry of Defense said on July 7, 2008 a group of up to ten militiamen were apparently prevented from placing mines on a Georgian-controlled by-pass road linking the Georgian villages in the north of Tskhinvali with the rest of Georgia. The Georgian side opened fire and the group was forced to retreat towards the nearby South Ossetian-controlled village. On July 8, 2008 South Ossetia reported that it had detained four "officers from the artillery brigade of the Georgian Ministry of Defense" close to the village of Okona in the Znauri district at the administrative border the night before.[20] Georgian President Mikheil Saakashvili told police to prepare an operation to free the four soldiers, but they were released before an operation was launched.[21]

Russian military jets flew into Georgian airspace through South Ossetia on July 9, 2008 and then returned to Russia. The next day, the Russian authorities confirmed the flight and said, in an official statement, that the fighters were sent to prevent Georgia from launching an operation to free the four soldiers detained by South Ossetia.[22] In response, Georgia recalled its ambassador to Moscow "for consultations", stating that it was "outraged by Russia's aggressive policies."[23]

The incident coincided with the visit of the U.S. Secretary of State Condoleezza Rice to Tbilisi where she pledged the U.S. support for Georgia's bid to join NATO. She said that granting NATO Membership Action Plan to Georgia would help resolve the Abkhaz and South Ossetian problems. The statement caused a negative outcry in Moscow: the Russian foreign minister Sergey Lavrov responded, during his meeting with the de facto Abkhaz president Sergey Bagapsh, that Georgia's NATO integration process "may undermine the conflict resolution" process.[24] On July 11, 2008, Georgian Deputy Foreign Minister Grigol Vashadze called for an urgent UN Security Council meeting on the conflict zones.[25]

A South Ossetian envoy on July 11, 2008 declared that South Ossetia was capable of repelling any attack by Georgia without help from Moscow and also said the mainly Russian peacekeeping contingent in the Georgian-South Ossetian conflict zone should be increased.[26] The Russian Ministry of Defense said in a statement the same day that measures have been taken "to increase combat readiness" of the Russian peacekeeping forces stationed in Abkhazia. It also said that security had been tightened at the Russian peacekeepers' base camps, observation posts and checkpoints, and "additional training" of the peacekeeping personnel had been conducted "to explain regulations of use of firearm while on duty."[27] Nika Rurua, Deputy Head of the Parliament's Security and Defense Committee, warned that Georgia would shoot down Russia's military aircraft in case they appear in its airspace again and an initiative was considered to this effect, but decided instead to appeal to the world community on the matter. Media reports published information about Russia's alleged plans to seize the Kodori Gorge specifying that the details of the operation were worked out by Russian high-ranking military officials, with Abkhazia's President Sergey Bagapsh. Russia reportedly considered responding[update needed] by revealing the details of a planned military invasion of South Ossetia by Georgia to release their detained officers.[28]

On July 14, 2008 Georgia's deputy defense minister Batu Kutelia said Georgia plans to expand its military more than 15 percent to 37,000 soldiers following events in Abkhazia and South Ossetia. The additional manpower would be used to defend Georgia's airspace and the Black Sea coast.[29] On July 15, 2008 the U.S. and Russia both began exercises in the Caucasus though Russia denies the timing was intentional.[30] The Russian exercises included training to support peacekeepers in Abkhazia and South Ossetia. Georgia claimed the exercises were a manifestation of Russian aggression against it.[31] Also on July 15, Abkhazia and South Ossetia were said to be planning to join the Union of Russia and Belarus, a spokesman for the Union said both regions have talked about joining the Union, but that they would need to be recognized as independent and become observers before they could join the Union as members.[32][33]

According to media reports, on July 19, 2008 a Georgian police post was attacked by Abkhaz militias using grenades, one of the militiamen died from a grenade exploding accidentally. Abkhaz officials condemned the reports as false.[34] Georgian media also reported on July 19 that a battalion of Russian troops had moved into the lower Kodori Gorge.[35] Georgia's Defense Ministry claimed Russian troops encroached on Mamison and Roksky passes in Abkhazia and South Ossetia respectively and are in combat alert. Abkhazia's Foreign Minister said no new troops were brought in over the quota.[36]

A U.N. report issued July 23, 2008 on the period between April and July 2008 noted discrepancies with the Georgian attack of a shooting in Khurcha on the day of Georgian elections. In particular the report noted the way the incident was filmed suggested the attack was anticipated. The report said reconnaissance flights by Georgia were a violation of the ceasefire, but said the shooting down of those fights also constituted a breach of the ceasefire. Concerning a military buildup by Georgia the UN report said it found no evidence of a buildup but noted observers were denied access to certain areas of Abkhazia controlled by Georgia including the Kvabchara Valley.[37]

On July 28, 2008 a spokesman for the Russian peacekeepers in South Ossetia said South Ossetian forces had blocked peacekeepers and OSCE observers from the village of Cholibauri which is close to where Georgia says South Ossetia is building fortifications.[38] On July 29, 2008 South Ossetia said two South Ossetian villages had been fired on by Georgian forces in response to South Ossetia reinforcing its positions on the perimeter of the conflict zone.[39] Georgia said the same day that Georgian posts on the Sarabuki heights were attacked by South Ossetian forces with no injuries reported.[38]
