Azerbaijan’s State Border Guarding Service says an Iranian national was wounded and arrested after a shootout between Azerbaijani border guards and a group of armed individuals.
Officials say the group tried "to illegally cross the border" with Iran, but they did not given the date of the incident.
The wounded Iranian, Ali Gurbanvend, 23, underwent surgery at an Azerbaijani clinic and is in satisfactory condition.
Azerbaijani border guards have issued an official protest note to the leadership at Iran's Aslanduz border checkpoint.
They are demanding a thorough investigation into the incident.
Tensions between Tehran and Baku escalated this year after Azerbaijan arrested a number of men with alleged links to Iran.
They were reported to be plotting attacks in Azerbaijan.
