Norway’s sovereign wealth fund, the world’s largest, said it had decided to exclude six companies with connections to the West Bank and Gaza from its portfolio, following an ethics review of its Israeli investments, Reuters reports.

The $2 trillion wealth fund did not name the companies it had decided to exclude, but said these would be made public, along with specific reasons for each company, once the divestment was completed.

The fund’s ethics council watchdog said it would continue to assess Israeli companies every quarter.
