At least 6-7 protesters were killed, and another 700+ were seriously injured. Ergo "several" butchered and "hundreds" maimed.
.
There is s difference between injured and maimed .... but let us not go into english language.
If 6-7 people are killed in a riot over 9 days (taking you figures on fcae value) ..... that you cannot define as butchering .......
If you take the killings that have happened in Pakistan in the last 9 days ..... then using your definition it can be termed as that a genocide is happening in Pakistan
