Authorities in breakaway Nagorno-Karabakh say 125 people were killed and hundreds more injured in an explosion at a packed gas station with people waiting for fuel to flee the enclave after the defeat of Armenian separatists last week. The regional health department upped the fatality total from 20 in a Tuesday evening update, although the cause of the blast at the gas station in Stepanakert was unknown. Thousands have fled the enclave after Azerbaijan seized key heights and junctions in a 24-hour offensive last week and Russian peacekeepers threw in the towel. The U.S. has called on Azerbaijan to maintain a ceasefire and protect the rights of civilians in the enclave as negotiations continue on its longer-term status within Azerbaijan.
