Azerbaijani President Ilham Aliyev visits a "War Trophy Park" showcasing military equipment seized from Armenian troops during the war over the Nagorno-Karabakh region. Yerevan ceded swathes of territories to Baku under a Russian-backed ceasefire, which was seen as a national humiliation in Armenia.

Prodding her cows forward with a long stick, Asya Petrosyan drives the herd along the snow-covered Lachin corridor, the last road out of Nagorno-Karabakh to Armenia. With Azerbaijani forces preparing to take back this district on Tuesday, the 67-year-old is rushing to bring 30 animals more than 55 kilometres (35 miles) to the town of Goris across the border in Armenia.

In an address to the nation, Azerbaijani President Ilham Aliyev says Armenia has "violated" the US-brokered ceasefire. But Armenia's defence ministry says Azerbaijani forces have violated the truce with artillery fire on combat positions in various parts of the frontline. A third attempt at halting weeks of fighting over Nagorno-Karabakh has collapsed quickly with Armenia and Azerbaijan trading accusations of violating the ceasefire within minutes.

Azerbaijani and Armenian forces battled for a second day after dozens were killed in an outbreak of heavy fighting that has raised fears of an all-out war between the longtime enemies.
