Ben Emmerson, a U.N. special rapporteur, is beginning an investigation into drone strikes in Afghanistan, Pakistan, Yemen, and Somalia, according to the Guardian.
“About 20 or 30 strikes – selected as representative of different types of attacks – will be studied to assess the extent of any civilian casualties, the identity of militants targeted and the legality of strikes in countries where the UN has not formally recognised there is a conflict.
“The inquiry will report to the UN general assembly in New York this autumn. Depending on its findings, it may recommend further action. Emmerson has previously suggested some drone attacks – particularly those known as "double tap" strikes where rescuers going to the aid of a first blast have become victims of a follow-up strike – could possibly constitute a 'war crime.'"
Several nations, including Pakistan, have requested the investigation.
