Israeli troops detained a senior Hamas legislator on Sunday, pushing forward with a crackdown on the Islamic militant group, Palestinian officials and relatives of the man said. Troops surrounded the home of Mahmoud al-Ramahi, secretary-general of the parliament, in broad daylight and detained him, said his sister, Yaqeen.? ? Al-Ramahi had evaded arrest since Israel began its crackdown on Hamas officials following the June 25 abduction of an Israeli soldier by Hamas-linked militants in the Gaza Strip. Israel is now holding five Cabinet ministers and more than two dozen lawmakers. The Israeli army had no immediate comment.
