A lawyer for a female Palestinian lawmaker says the Israeli military has placed the legislator under detention for six months without trial.

Mahmoud Hassan said Monday that Khalida Jarrar, a senior political leader of a left-wing Palestinian militant group, is being held for alleged activities in a hostile organization.

He says Jarrar is being held under Israeli administrative detention, which allows Israel to hold detainees for up to six months at a time without charges.

A Palestinian prisoners' advocate, Qadoura Fares, says the arrest is political. He says Israel is holding 16 Palestinian lawmakers in jails.

The Israeli military arrested Jarrar last week for disobeying an Israeli order barring her from the West Bank city of Ramallah. The military had no immediate comment Monday on the six-month detention.
