A member of the Palestine Liberation Organization (PLO) parliament has been sentenced to 15 months in jail by an IDF military court, the military confirmed on Monday, for her role in planning a terrorist attack.

Khalida Jarrar, a senior member of the communist Popular Front for the Liberation of Palestine (PFLP) terrorist organization, was sentenced on Sunday at the Ofer military court located north of Jerusalem.

She had been arrested in April on a series of charges, including encouraging terrorist attacks against Israel and violating a travel ban, and in June a judge nixed her possibility of release after incriminating testimony was submitted.

"Jarrar was sentenced to 15 months on the charges she was arrested for a few months ago, including incitement of terrorism," an IDF spokesperson told AFP on Monday.

The period since April will be considered part of her sentence, meaning she is likely to remain in jail until next summer. The Palestinian Arab prisoner rights group Addameer said she had also been fined 10,000 shekels ($2600, 2400 euros) and given a five-year suspended sentence.

At the time of her arrest the IDF warned that Jarrar posed "substantial security risks."

She was accused of 12 security crimes, including inciting to abduct IDF soldiers so as to negotiate the release of jailed Arab terrorists. Among the terrorists she sought to free was Ahmad Sa'adat, the leader of PFLP who was sentenced to 30 years in jail in 2008 for heading the terrorist group.

Sa'adat was accused of planning the 2001 assassination of Tourism Minister Rehavam "Gandhi" Ze'evi, which was committed by four PFLP terrorists in Jerusalem; the Palestinian Authority (PA) has lauded Sa'adat on numerous occasions for the murder.

Following Jarrar's sentencing on Monday, PA minister for prisoner affairs Issa Qaraqe condemned the trial, calling it "arbitrary and legally unjustified."

"This is a political arrest. The charges against her are fabricated and ridiculous...there are no security reasons as claimed by the Israeli authorities," he claimed to AFP.

Jarrar is a member of the PLO parliament which has not met since 2007 after elections a year earlier were won by the Hamas terrorist organization.

In August 2014 she was ordered to leave Ramallah within 24 hours and to move to Jericho, but announced at the time she would disobey it.
