evidence: When Mirziyaev took over as Uzbekistan's leader on September 8, Uzbek police had been occupying a hill in Kyrgyzstan, Ungar-Too, for more than two weeks. The Uzbek forces detained four Kyrgyz nationals who were working at the television relay station on Ungar-Too and refused to free them, angering Kyrgyz villagers in the area and the government in Bishkek. [...] On September 20, the Uzbek police withdrew from Ungar-Too. The same day, the pro-government website Uzdaily.uz reported that from September 14 to 20 a working group of officials from both countries had been reviewing questions of border demarcation in 23 disputed areas along the common frontier.
