The son of a Pro-Palestinian activist has said he "remains in the dark" after she was detained in the occupied West Bank.
Deirdre Murphy, who lives in Swansea, has been held in custody since 31 May when she was arrested in a southern part of the territory.
The 70-year-old, originally from Cork, Ireland, had been volunteering with the pro-Palestinian activist group International Solidarity Movement (ISM) at the time of her arrest. The Israeli government has been approached for comment.
Torsten Bell, Labour MP for Swansea West, said he would do everything he can "to support a swift and just resolution" after raising concerns about Ms Murphy's access to legal representation.
The West Bank – the land between the eastern edge of Israel and the western side of the River Jordan – is home to an estimated three million Palestinians.
Israel has occupied the West Bank – which Palestinians want as part of any future state – since the Six Day War of 1967, and is continuing to build settlements in the area.
