Al-Jazeera says Samer Allawi, its bureau chief in Afghanistan, was taken into custody on Aug. 10 as he tried to leave the West Bank to return to the Afghan capital, Kabul.

The Committee to Protect Journalists in New York says Allawi has been detained without charges and called on Israel to clarify the legal basis for holding him.

The Israeli military, Shin Bet internal security service and police on Tuesday had no comment on the arrest.

Al-Jazeera says Allawi was in the West Bank for a vacation with his family in his native village of Sebastia.
