Israel on Tuesday ordered senior Hamas official Aziz Dweik, speaker of the Palestinian parliament, to be held without trial for six months, according to his lawyer.
The IDF arrested Dweik at a checkpoint near the West Bank city of Ramallah last week. The IDF said he was suspected of involvement with terrorist groups.
"The (administrative detention) order was issued today but as is almost always the case, it gave no specific reasons why Dweik should be held. It said only that he was being detained because he was liable to be involved in hostile actions against Israel," lawyer Fadi Kawasmi told Reuters.
An IDF spokesman said he was checking for details of the case. Israel previously arrested Dweik in 2006 and held him in jail for two years.
