What the sources establish
UNHCR carries the official instrument or communique. Reuters records the same dated act independently.
Established: A mass departure of ethnic Armenians from Nagorno-Karabakh was recorded from 24 September 2023 by UNHCR/ICRC neighbourhoods.
UNHCR counted arrivals. This page does not invent a size.. A later repeal, court stay, or successor order would be a different Fact with a different date. That pair identifies Ethnic Armenians leave Nagorno-Karabakh after the 19 September operation, not a later speech about Ethnic Armenians leave Nagorno-Karabakh after the 19 September operation.
Co-authors and later implementers named in Context remain on the file. If a later repeal, stay, or successor instrument exists, it needs its own date and its own row. The contribution described on this Person row is limited to He commanded the operation that preceded the flight. UNHCR counted arrivals. This page does not invent a size. That limit is the alternative to treating office-holding as authorship of every later series.
