Armenia's Defense Ministry said four soldiers were killed and four more wounded in a clash with Azerbaijani forces in the disputed enclave of Nagorno-Karabakh. The ministry said that fighting erupted late Friday after a group of Azerbaijani soldiers tried to enter Nagorno-Karabakh, a mountainous region that is a part of Azerbaijan but has been under Armenian control since 1994, AP reported. Defense Minister Edvard Nalbandyan said Saturday that the attack was repelled and the Azerbaijani forces retreated.
