Three of Azerbaijan's troops have been killed in the past 24 hours in fighting with the separatist region of Nagorno-Karabakh, the defence ministry said.
Vagif Dargyakhly, the ministry's spokesman, said the rebels were shelling Azerbaijian's positions and front-line villages despite a ceasefire his government unilaterally announced.
Nagorno-Karabakh has been under the control of local ethnic Armenian forces and the Armenian military since a war ended in 1994 with no resolution of the region's status.
Fighting flared up there over the weekend with a boy and at least 30 troops killed on both sides on Saturday, the worst fighting since the end of a full-scale war in 1994.
On Sunday, Azerbaijan said it had unilaterally ceased fire but the rebels in Nagorno-Karabakh said their positions were still under attack.
In the autumn of 1915, an Austrian engineer called Litzmayer, who was helping build the Constantinople-Baghdad railway, saw what he thought was a large Turkish army heading for Mesopotamia. But as the crowd came closer, he realised it was a huge caravan of women, moving forward under the supervision of soldiers.
The photographs, never before published, capture the horrors of the first Holocaust of the 20th century. They show a frightened people on the move – men, women and children, some with animals, others on foot, walking over open ground outside the city of Erzerum in 1915, at the beginning of their death march.
