 :* For WP:SYNTH, this source from the lead talks about all 7 incidents. 
 :* As for Israel's response, there is a long quote by IDF spokesperson in the lead, talking about abuse of UN facilities, militants operating in the area etc. 
 :* As the source indicates, the likelihood (of course nothing is sure) is that it was Israeli shelling which hit all the shelters, and not other munitions. There was one incident which was initially disputed, but over time the view has become clear that it was Israeli shelling. 
 :* Lastly, militants operating in the area/human shields etc. is present in the background section.
