The Haifa District Court on Sunday gave the Israel Prison Service one day to respond to a petition challenging the detention of Al-Jazeera journalist Samer Allawi.

Allawi was arrested on Aug. 10 while attempting to cross the border from the West Bank into Jordan. According to Al-Jazeera, the reporter, a Palestinian who holds a Jordanian passport, was on his way back from a three-week vacation in the West Bank with his family. Allawi works in Afghanistan, where he serves as Al-Jazeera's bureau chief.

While no official charges have been filed against him, Israeli authorities reportedly told the military court that he is suspected of being a member of Hamas.

Allawi's attorney Salim Wakim told the Huffington Post in August that his client was interrogated by investigators who attempted to pressure him into acting as an informant for Israel. According to Wakim, Allawi was grilled about his work, finances and personal relationships. He also said that Israeli authorities cited a secret intelligence report during the court proceedings.

Al-Jazeera, which has repeatedly called for Allawi's release, has said he was arrested "without reason."

Several international media rights organizations, including Reporters without Borders and the Committee to Protect Journalists, have also condemned his continued detention.

Around 150 Palestinian journalists demonstrated outside the U.N.'s offices in Gaza City on Saturday calling for Allawi's immediate release, and describing his detention as "arbitrary" and a blow to freedom of the press.
