An Israeli court on Friday extended the administrative detention of Palestinian legislator Issa Khairy al-Jabari, a Ma'an correspondent said.
The Hamas member will serve another four months in an Israeli prison on the basis that he poses a threat to security.
Al-Jabari was arrested by Israeli forces in May 2011, having been released from Israeli custody in March 2010, after 14 months in jail.
He was also detained in the summer of 2006, when Israeli forces rounded up Hamas officials in response to the capture of a soldier by a militant group in Gaza.
He was held for almost two years and re-arrested in 2009.
Al-Jaabari was elected to the Palestinian Legislative Council in 2006.
