Comments over the weekend from the leader of the pro-Kurdish Peoples' Democratic Party (HDP) were a "clear provocation" and the party "will be taught a lesson" by the people and the law, President Tayyip Erdogan said in a live broadcast on Tuesday. A Turkish prosecutor opened an investigation into HDP head Selahattin Demirtas for calls for greater Kurdish self-governance, Dogan news agency reported on Monday. Demirtas, a lawyer turned politician, was one of the participants in a two-day congress of Kurdish groups this weekend that called for more self-governance. http://english.ahram.org.eg/News/177653.aspx
