Azerbaijan says Armenian forces shell second city in escalation of week-long conflict

Azerbaijan said on Sunday that Armenian forces had shelled its second city of Ganja in an escalation of the war in the South Caucasus that broke out one week ago.

Armenia denied that it had directed fire "of any kind" towards Azerbaijan, but the leader of Nagorno-Karabakh, an ethnic Armenian enclave inside Azerbaijan, said his forces had destroyed a military airbase in Ganja.

The escalation carries the risk of a full-scale war between the former Soviet republics of Azerbaijan and Armenia that could drag in other powers. Azerbaijan is supported by Turkey, while Armenia has a defense pact with Russia. Fighting that broke out one week ago between Azeri and ethnic Armenian forces has intensified in the past two days and spread way beyond the breakaway Karabakh region.

"Delivering fire on the territory of Azerbaijan from the territory of Armenia is clearly provocative and expands the zone of hostilities," Azeri Defense Minister Zakir Hasanov said.

Ganja, with a population of 335,000, is about 100 km (60 miles) north of the Karabakh capital Stepanakert and 80 km from the Armenian city of Vardenis. Azerbaijan has previously accused Armenia of firing into its territory from Vardenis, and Yerevan has denied it.

Armenia says Azerbaijan has used the airport in Ganja as a base for its warplanes to carry out bombing raids on Nagorno-Karabakh.

Nagorno-Karabakh leader Arayik Harutyunyan said his forces would target Azeri cities.

"Permanent military units located in the large cities of Azerbaijan from now on become the targets of the defense army," he said.

HEAVY CASUALTIES

Casualties from the past week's fighting have run into the hundreds, although precise figures are impossible to obtain.

Armenia said the Karabakh cities of Stepanakert and Martakert were under attack by Azerbaijan's air force and from long-range missiles.

Each side accused the other of targeting civilians.

Ignoring appeals from Russia, the United States, France and the EU to call a ceasefire, the opposing sides have stepped up hostilities over the weekend, with an accompanying rise in aggressive rhetoric.

Armenia said on Saturday it would use "all necessary means" to protect ethnic Armenians from attack by Azerbaijan, and its prime minster compared the struggle with a 20th century war against Ottoman Turkey.

Azerbaijan said on Saturday its forces had captured a string of villages. Armenia acknowledged that ethnic Armenian fighters were under pressure in some places and said the situation on the ground was fluctuating.

The clashes are the worst since the 1990s, when some 30,000 people were killed. They have raised international concern about stability in the South Caucasus, where pipelines carry Azeri oil and gas to world markets.
