There's two "main" definitions of genocide, which both origins with Raphael Lemkin, the author and activist who made it his life's work to cement it as a concept in law and morality:
1. The UN Genocide resolution definition; which is a limited vision of Lemkin's ideas mainly encompassing actions with murderous intent. This is also the internationally acknowledged legal definition of genocide as a crime.
2. Lemkin's full vision of what encompassed genocide, which aside from mass murder of people and similar also included cultural side of genocide, the targeting of "national identity cornerstones, the oppression of languages, and similar. The part that makes genocide a murder of the genos, the concept of a people, as opposed to a straight mass murder of persons. Lemkin felt that the UN had failed to take this part seriously and often cited the Holodomor as a genocide that went beyond simply the killing of Ukrainians but a direct attack on the Ukrainian identity, the Ukrainian genos, and the ability of the Ukrainian people to continue being Ukrainian. To directly quote the
wikipedia article on the Holodomor rather than blather on myself:
According to Lemkin, Ukraine was "perhaps the classic example of Soviet genocide, its longest and broadest experiment in Russification – the destruction of the Ukrainian nation". Lemkin stated that, because Ukrainians were very sensitive to the racial murder of its people and way too populous, the Soviet regime could not follow a pattern of total extermination (as in the Holocaust). Instead the genocidal effort consisted of four steps: 1) extermination of the Ukrainian national elite, 2) liquidation of the Ukrainian Autocephalous Orthodox Church, 3) extermination of a significant part of the Ukrainian peasantry as "custodians of traditions, folklore and music, national language and literature", and 4) populating the territory with other nationalities with intent of mixing Ukrainians with them, which would eventually lead to the dissolution of the Ukrainian nation.[147][148] The "rediscovery" of Lemkin's 1953 address about the Holodomor has influenced Holodomor scholars, especially his view of genocide as a complex process targeting institutions, culture, and economic existence of a group and not necessarily meaning its "immediate destruction".
It is likely that you can sense from how much more I lingered on it that, yes, I feel definition 2 and Lemkin's full design to be the most complete definition of the term.
"Ethnical cleansing" through deportation or coerced eviction, is not an outright part of definition 1, but it is part of definition 2. In my mind, Israel's settlement policies is a case of ethnical cleansing, and thus genocide.
When it comes to the deliberate targeting of the places they told civillians to go, I so find this to be a breach of even definition 1, however (Disclaimer: I only read the headlines of the article). In my mind, this is even more a case of definition 1 than it would have been if they had not told people to go there and then killed the same people or even more civillians in their bombing of the places they came from, specifically because the order of civillians to seek shelter in these places.
