Three Armenian and two Azerbaijani soldiers have been killed in fighting on the border of Azerbaijan's breakaway region of Nagorny Karabakh, Azerbaijan's defence ministry said Wednesday. Baku accused Armenian forces of attacking its positions near village of Chaily in the Terter region of Azerbaijan around at 16.30 pm (2130 GMT) on Tuesday, the ministry said in a statement. 'Azerbaijani servicemen repulsed the attack. Three Armenian and two Azerbaijani soldiers were killed as a result,' it said. The Armenian authorities could not immediately be reached for comment. Tensions over Karabakh have risen in recent months amid stalled negotiations over the status of the region, where ethnic Armenian separatists backed by Yerevan seized control from Baku in a bloody war of secession in the 1990s. Armenian and Azerbaijani forces are spread across a ceasefire line in and around Nagorny Karabakh, often facing each other at close range, and shootings are common.
