Hiermee kan de Shahed verbinding maken met het mobiele netwerk, waardoor de operator beelden kan ontvangen. Achtergrond: www.forbes.com/sites/davidh...

Yes, Ukraine has long faced corruption. But turning this into a weapon against Ukraine is hypocritical. Who’s blaming us? Orban (Hungary is a most corrupt in EU)? Trump? MGT? 😆 Ruzzians ranked far below us?🤔 Ukraine climbed 50 places in the index in recent years - that’s real progress! Be fair!👍

Dasha did not expect to serve. She spent the first months of the invasion helping as a volunteer, then moved into drone work as more men from her region were killed or mobilised. “It wasn’t about whether I was ready,” she says. “It was about the fact that there were fewer people left.”

Trollenlegers uit buitenland versterkten politieke en opruiende berichten rond verkiezingen
Honderden nepaccounts op sociale media hebben rond de Nederlandse Tweede Kamerverkiezingen vanuit Nigeria, Ghana en andere landen het debat benvloed door politiek getinte berichten en accounts te versterken. Dat zeggen deskundigen in reactie op onderzoek van RTL Nieuws. Door berichten te delen en massaal kleine accounts te volgen, hebben de nepaccounts volgens de experts uiterst rechtse en antiinstitutionele standpunten populairder laten lijken dan ze waarschijnlijk zijn.
