(YEREVAN, Armenia) — Fighting erupted anew Sunday between Armenia and Azerbaijan over the disputed separatist region of Nagorno-Karabakh. Armenia said a woman and a child were killed in the area by shelling from Azerbaijani forces and Azerbaijan’s president said his military has suffered losses. Armenia also claimed that two Azerbaijani helicopters were shot down and three Azerbaijani tanks were hit by artillery, but Azerbaijan’s defense ministry rejected that claim. Heavy fighting broke out in the morning in the region that lies within Azerbaijan but has been under the control of ethnic Armenian forces backed by Armenia since 1994 at the end of a separatist war.
