The Armenian military reported Friday that one of its soldiers was killed and eight more were wounded in yet another clash with Azerbaijani forces on the border between the two countries, where tensions have simmered for months.

Armenia's Defense Ministry blamed the casualty on "aggressive actions" by Azerbaijan's troops, alleging they attacked Armenian positions on the eastern section of the border. The Azerbaijani Defense Ministry, in turn, claimed Armenian forces opened fire first.

Both countries reported a similar clash on Thursday, with Azerbaijan reporting one casualty and Armenia saying two of its troops sustained injuries.
