Israeli settlers beat up one of the Palestinian co-directors of the Oscar-winning documentary film No Other Land on Monday in the occupied West Bank before he was detained by the Israeli military, according to two of his fellow directors and other witnesses.

The filmmaker Hamdan Ballal was one of three Palestinians detained in the village of Susiya, according to attorney Lea Tsemel, who is representing them. Police told her they were being held at a military base for medical treatment, but she said on Tuesday morning that she had not been able to reach them and had no further information on their whereabouts.
