Earlier this month, Al Haq’s researcher at the ICC, Nada Kiswanson, told the Dutch press that she had received death threats and other intimidations for several months, including letters, emails and phone calls to her home and family members. A man phoned Kiswanson’s family members in Sweden and, in heavily accented Arabic, told them she would “disappear” if her work at the ICC continued, Jabarin said.

Kiswanson also received a call from a woman purporting to be from the Dutch Health Ministry, who asked for her home address to send her a survey and information about the Zika virus. Shortly thereafter, Kiswanson received flowers at her door, a threatening note attached to them. Jabarin said the delivery originated in Amsterdam


n addition, Al Haq’s international donors have received calls alleging that the organisation was being investigated for corruption, while faked internal emails told staff members that the organisation was having funding problems and that they should find new jobs, he said.

Dutch authorities have been investigating the Kiswanson case, but Al Haq did not have any information about potential suspects for that or any of the other incidents.

“Israel is behind it,” Jabarin alleged. “Criminals, all the time, they are afraid. When you start searching and looking to identify them, they will become afraid. For them, it’s easy to defeat politicians, but it’s not easy for them to defeat the human rights defenders.”

A spokesperson for the Israeli prime minister’s office did not respond to Al Jazeera’s request for comment on the allegations. Emmanuel Nahshon, a spokesperson for the Israeli Ministry of Foreign Affairs, said in a curt email: “We do not react to such preposterous allegations.

Al Haq is not the only Palestinian rights group to receive threats recently.

Gaza-based organisation Al Mezan said in a news release this month that its workers have faced “a protracted campaign of intimidation, harassment and threats” since last year, including suspicious emails and Facebook messages, along with calls to staff and donors.

“Recently, the campaign against Al Mezan became much more serious, much more explicit, involving death threats against one of our staff members, in particular, and death threats against his family,” said Nuriya Oswald, Al Mezan’s international advocacy coordinator, noting that the email threat contained recent images of the staff member’s house taken at close range.

Oswald told Al Jazeera that most of the threats were levied against Al Mezan staff while they were working in Europe, with local police investigating threats in three separate countries. While the perpetrators have not been identified, the threats seem to be related to Al Mezan’s accountability work, she said

Death threats against individuals working at the ICC have intensified recently because that effort “is becoming more tangible [and] more organisations are working together”, Tartir said.

“This is a worrying sign for Israel and its friends, so this is why they are doing what they are doing now,” he said, adding that the international community must ensure human rights defenders are protected and freely able to do their work.

Palestinian human rights workers will continue with their work, despite the intimidation, Jabarin added.

“For us, working in human rights is a belief. It’s faith … Defending justice and looking for justice is not a job. We know that we will face difficulties, we will face challenges,” he said. “And we are ready
