Norway’s finance minister has ordered a review of investments by the country’s wealth fund in companies active in the Palestinian territories after Israel’s crackdown in Gaza, officials said.

The $300bn (€222bn, £202bn) oil fund, officially known as the Government Pension Fund – Global, invests under ethical guidelines from the ministry of finance and has excluded a few dozen companies that produce nuclear arms or cluster munitions, degrade the environment or violate human or worker rights.
