VIENNA (Reuters) - Soldiers from Azerbaijan and Nagorno-Karabakh were killed early on Tuesday, hours after the Armenian and Azeri presidents agreed on the need for a peaceful settlement to the conflict in the breakaway region where violence flared again last month.

Monday's meeting between Armenian President Serzh Sarksyan and Azeri President Ilham Aliyev in Vienna was the first since fighting between Armenian-backed separatists in Nagorno-Karabakh and Azeri forces restarted. The resurgence in violence has killed dozens of people and pushed relations between the neighbours to their worst in years.
