– Heavy fighting erupted Sunday between Azerbaijan and Nagorno-Karabakh forces over the separatist region of Azerbaijan’s territory, the AP reports. According to Reuters, Nagorno-Karabakh said 16 of its servicemen were killed and more than 100 wounded after Azerbaijan launched an air and artillery attack early Sunday. Armenia and Nagorno-Karabakh declared martial law and mobilized the male population. Azerbaijan, which also declared martial law, said its forces responded to Armenian shelling and that five members of one family had been killed by Armenian shelling. It also said its forces had seized control of up to seven villages. Nagorno-Karabakh initially denied that but later acknowledged losing ‘some positions’ and said it had suffered a number of civilian casualties, without giving details. The clashes prompted a flurry of diplomacy to reduce the new tensions in a decades-old conflict over Nagorno-Karabakh, a breakaway region that is inside Azerbaijan but is run by ethnic Armenians. Nagorno-Karabakh broke away from Azerbaijan in a conflict that broke out as the Soviet Union collapsed in 1991. Although a ceasefire was agreed in 1994, after thousands of people were killed and many more displaced, Azerbaijan and Armenia frequently accuse each other of attacks around Nagorno-Karabakh and along the separate Azeri-Armenian frontier. In Sunday’s clashes, Armenian right activists said an ethnic Armenian woman and child had also been killed. Armenia said Azeri forces had attacked civilian targets including Nagorno-Karabakh’s capital, Stepanakert, and promised a ‘proportionate response.’
