A group of 10 human rights groups told The Hague district court on Friday the Netherlands is violating international law by continuing trade with Israel, demanding the government stop weapons exports to Israel and cut trade with the occupied territories.

The hearing comes one day after the International Criminal Court issued arrest warrants for Israeli prime minister, Benjamin Netanyahu, former defence minister Yoav Gallant and the Hamas leader Mohammed Deif for alleged war crimes in the Gaza conflict.

The groups, who filed the lawsuit in October, base their claim on the 1948 Genocide Convention, which requires countries to “prevent and punish genocide.”

“The list of Palestinian victims grows longer every day and the unbelievable suffering of the victims and their relatives can no longer be put into words,” lawyer Wout Albers, who is representing the group, said.

The Dutch government denies it is violating international law and asked the court to dismiss the case. Government lawyer Reimer Veldhuis said it isn’t for the court to decide foreign policy.

“Dutch weapons are being used to kill children in Palestine, including my family,” Ahmed Abofoul told the court. He is a legal advisor for Al-Haq, one of the groups involved in the suit.

Foreign affairs minister Caspar Veldkamp has scrapped next week’s visit to Israel and the Middle East in the wake of the ICC decision. Veldkamp told parliament on Thursday the Netherlands would arrest Netanyahu if he set foot on Dutch soil, in line with the ICC’s position.

The Netherlands will also not engage in any “non-essential” contacts with Netanyahu, former defence minister Yoav Gallant and Hamas leader Mohammed Deif, Veldkamp said.
