SodaStream CEO Daniel Birnbaum on West Bank factory

Hollywood actress Scarlett Johansson has stepped down as an Oxfam ambassador after criticism of her support for Israeli company SodaStream.

The charity said the actress's role was incompatible with being an Oxfam Global Ambassador.

A spokesman for the actress said she had a "fundamental difference of opinion" with the humanitarian group.

She will remain a brand ambassador for SodaStream, which has a factory in the Jewish settlement of Maale Adumim.

The BBC's Kevin Connolly spoke to the CEO of SodaStream, Daniel Birnbaum.
