Palestinian Arab lawmaker Khalida Jarrar was on Thursday ordered detained for six months by Israeli authorities, AFP reported, citing a rights group.

Jarrar, a senior member of the Popular Front for the Liberation of Palestine (PFLP) terrorist organization, was arrested earlier this month, and not for the first time.

She had previously been arrested in April of 2015 on a series of charges, including encouraging terrorist attacks against Israel and violating a travel ban.

She was later sentenced to 15 months in prison for planning an abduction of Israelis in an attempt to use them to free jailed terrorists, before being released last June.

According to the Addameer NGO, Jarrar was given a six-month administrative detention order.

A confirmation hearing will be held at Ofer military court on July 17, Addameer said.

The detention "constitutes an attack against Palestinian civil society leaders", the movement said.

The IDF said Jarrar was arrested on July 2 and that a six-month administrative detention order was issued against her because of her activities "as an important official of the Popular Front for the Liberation of Palestine, a terrorist organization".

In a statement it said such orders are issued as a preventive measure of last resort in cases where detainees represent "a serious and concrete threat to security".

Jarrar was previously 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 Ze'evi, which was committed by four PFLP terrorists in Jerusalem.
