Israeli soldiers raided three Palestinian nongovernmental organizations in Ramallah before dawn on Tuesday, seizing computers and other equipment from two of them: Addameer, which supports Palestinian prisoners in Israeli jails, and the Union of Palestinian Women Committees. The offices of the Palestinian NGO Network, an umbrella group that assists dozens of local organizations working in fields like health, agriculture and human rights, located in the same building as Addameer, were also ransacked. An Israeli military spokesman said the offices were searched because they were affiliated with the Popular Front for the Liberation of Palestine, a leftist militant group that Israel and others classify as a terrorist organization. A spokesman for Addameer strongly denied any such links.
