Building on its relationship with community centres in New York and Jerusalem, Jewish Care's Redbridge Jewish Community Centre hosted a week of activities for teens from London, America and Israel.
As well as seeing the sights of the capital, participants had practical and theoretical workshops to help them develop leadership skills.
"It was both fun and a real learning experience," said Israeli Yael Malul. "I made some great new friends but also think I got a taste of what it means to be a leader."
Organisers Naomi Shaanan and Joy-Caron Canter said the scheme reflected "the idea behind the tri-partnership to link Jewish communities around the world in order to learn more from each other and deepen our Jewish roots and heritage".
