US President Biden says downed objects likely not related to espionage

US President Joe Biden has finally spoken about the Chinese balloon saga and three other unknown aerial objects shot down by US fighter jets in recent days. It all started when a gigantic white balloon -- suspected to be a Chinese surveillance device -- was shot down in early February -- putting North American security forces on high alert. Since then, three other -- much smaller -- objects were spotted over Canada and the US states of Alaska and Michigan ---and shot down as well. Biden has now broken his silence about the unknown aerial objects.
