Khalida Jarrar was arrested on July 2 for being a senior member in the Popular Front for the Liberation of Palestine (PFLP).

:: Israel has extended the detention without trial of a prominent Palestinian politician by another six months, the army said Tuesday, meaning she will spend at least one year in custody.

Khalida Jarrar was arrested on July 2 for being a senior member in the Popular Front for the Liberation of Palestine (PFLP), a movement considered a terrorist organization by Israel, the United States and the European Union.

She had been released from prison only a year before.

Details of the accusations against her are secret, as is customary with Israeli administrative detention orders, which allow detention without trial for renewable six-month periods.

A legislator in the largely defunct Palestinian parliament, she was given a six-month administrative detention order in July.

On December 24, the detention was extended by another six months “after security personnel found she still poses a substantial threat,” the Israeli army said.

“The decision to hold Jarrar under administrative detention was made as a last resort, after the military official who signed the arrest warrant was displayed confidential information that clearly substantiates the threat posed by Jarrar,” the army said in a statement.

Many PFLP leaders are in custody and Jarrar has been jailed multiple times.

The 54-year-old had only been released in June 2016 after 14 months in an Israeli jail for allegedly encouraging attacks against Israelis.

Israel says administrative detention is intended to allow authorities to hold suspects while continuing to gather evidence, with the aim of preventing attacks in the meantime.

But the system has been criticized by Palestinians, human rights groups and members of the international community who say Israel abuses the measure.
