Azerbaijan claims 'full control' of border with Iran
The Nagorno-Karabakh region of Azerbaijan is controlled by Armenians, backed by Yerevan, who declared independence as the Soviet Union fell in a conflict that erupted again into full-scale fighting last month.
But President Ilham Aliyev said that with the capture of a settlement named Agbend, Baku now had full control of the border with Iran.
Azerbaijan has repeatedly boasted of military gains in the more than three weeks of fighting and on Wednesday Armenian Prime Minister Nikol Pashinyan acknowledged his country was facing "a difficult situation" on the frontline.
Baku has never hidden its desire to regain full control over Karabakh and the seven regions. But analysts say it will struggle to achieve this by military means alone.
Yet diplomacy also appears exhausted for now, with Pashinyan ruling out any diplomatic solution to the conflict for the moment and both sides further entrenching in their positions.
Yet hopes of a genuine ceasefire are fragile after two truces agreed over the last fortnight never showed any semblance of holding on the ground.
Meanwhile, the toll continues to mount.
Yerevan says 874 Armenian soldiers and 36 civilians have been killed in the flare-up of fighting.
Baku has reported 63 civilian casualties but has yet to disclose military losses.
In an interview with AFP, the head of an International Committee of the Red Cross (ICRC) mission monitoring the conflict urged all parties to stop shelling civilians.
"We insist that the sides to the conflict comply with international humanitarian law," Gerardo Moloeznik said.
