Weaponizing ordinary communication devices represents a new development in warfare, and targeting thousands of Lebanese people using pagers, two-way radios and electronic equipment without their knowledge is a violation of international human rights law, the United Nations human rights chief said Friday. Volker Türk told an emergency meeting of the U.N. Security Council there must be an independent and transparent investigation of the two attacks in Lebanon on Tuesday and Wednesday where these devices exploded, reportedly killing 37 people and injuring more than 3,400 others.
