At least four Armenian soldiers die in an exchange of fire on the border with Azerbaijan. Both countries accuse each other of having shot first in the most serious incident since they agreed in December to advance their peace negotiations.
The fighting began at 5:30 local time (2:30 in mainland Spain) when “units of the Azerbaijani Armed Forces opened fire with light weapons” against Armenian positions in the outskirts of Nerkin Hand, at the southern end of the border that separates both countries.
