RAMALLAH, West Bank — Palestinian activists and human rights groups have called on Israel to allow a prominent jailed lawmaker to attend her daughter’s funeral on Tuesday.

Khalida Jarrar, 58, a leading member of the Popular Front for the Liberation of Palestine, has been in and out of Israeli prison in recent years and was sentenced to two years in March for being a member of an outlawed group. With time served, she is set to be released in October.

The PFLP has an armed wing and is considered a terrorist group by Israel and Western countries, but Jarrar has not been implicated in attacks. The Israeli military acknowledged in March that she “did not deal with organizational or military aspects of the organization.”

Jarrar was sentenced to 15 months in 2015 on charges of incitement and membership in the PFLP. She has also been held for months at a time in what’s known as administrative detention, under which Israel detains Palestinian suspects for lengthy periods without charge.

Her 30-year-old daughter Suha, who worked on issues related to gender and climate change for the Al-Haq human rights group, was found dead on Sunday in her home in the occupied West Bank city of Ramallah, the group said. It did not give a cause of death.

Al-Haq launched a campaign calling for Khalida’s “immediate and unconditional release on humanitarian grounds,” and said it had appealed to other countries as well as the International Committee of the Red Cross.

Entreaties poured in from other activists and rights groups in an online campaign under the hashtag #freekhalidajarrar. An online petition drew more than 11,500 signatures.

Israeli officials declined to comment.

The New York-based Human Rights Watch said Jarrar’s repeated arrests are part of Israel’s wider crackdown on non-violent political opposition to its half-century military occupation of lands the Palestinians want for a future state.

“Detaining Khalida over her political activism violates her freedom of association,” said Omar Shakir, the group’s director for Israel and the Palestinian territories. “Having repeatedly detained Khalida in violation of her rights, Israeli authorities should at minimum allow her to say goodbye to her daughter.”
