evidence: The clashes broke out this week along the frontier between Tajikistan’s Sughd province and Kyrgyzstan’s southern Batken province because of a dispute over a reservoir and pump, claimed by both sides, on the Isfara River. [...] On Saturday, the AFP news agency said its correspondent in Batken was unable to reach the conflict area because Kyrgyz men holding stones were turning back cars on a road lined by Kyrgyz soldiers between the village of Min-Bulak and the town of Isfana. [...] Border disagreements between the three countries that share the fertile Fergana Valley – Kyrgyzstan, Tajikistan and Uzbekistan – stem from demarcations made during the Soviet era.
