The Netherlands suspended its contribution to the UN agency for Palestinian refugees pending the outcome of a probe into alleged mismanagement and abuses of authority by the agency' top management.

The Dutch decision comes a day after a similar move by Switzerland, which said it would suspend additional contributions.

The report by the agency’s ethics department revealed a series of allegations relating to sexual misconduct, nepotism and discrimination.

The Netherlands expressed "its great concern and asked for clarification," the Dutch foreign ministry said in a statement.

Sigrid Kaag, foreign trade and development cooperation minister, said the statement "would like to hear what steps the UN plans to take based on the outcome of the investigation."

The Swiss Foreign Ministry said the government had already sent its annual contribution of $22.5 million to the agency but it would not give “any additional contributions”.

UNRWA, led by Swiss national Pierre Krahenbuhl, has declined to comment in detail on the internal report while the UN probe is ongoing. UN Secretary General Antonio Guterres is “committed to acting swiftly upon receiving the full report”, the global body’s spokesmanFarhan Haq told reporters in New York on Tuesday.
