Honestly, from one article in the OP we're not going to know the whole story here. What happens between Israel and Palestinians is complex and has al sorts of context.
The article basically says activists came to rebuilt Palestinian roads that were damaged, the Israeli military showed up and said you have 10 minutes to go away or we'll arrest you, the activists disobeyed them and so were arrested. We don't know the context. Is Israel just being dicks & trying to make Palestinian's lives a living hell? Or were some using these village roads for terrorist operations or some other reason we don't know about? Like we don't know, who the hell but Mossad knows WTF is going on.
IMO if you're an activist and want to help that's ok but when soldiers start showing up I'd take their threats seriously and GTFO and go help somewhere else, even if I didn't agree with it, who the hell wants to be a martyr?
