This is the world in brief from the Economist. Our top stories. Armenia said that over 50,000 ethnic Armenians had fled from Nagorno-Karabakh into the country since Azerbaijan took control of the enclave last week. The figure represents over one-third of Nagorno-Karabakh's population. Azerbaijan arrested Rubin Vardanian who led the enclave's separatist government until February as he tried to flee into Armenia. Azerbaijan said that 192 of its troops had been killed during the military operation to regain full control of Nagorno-Karabakh, which had been run by Armenian separatists for three decades.
