ILIGAN CITY: Davao City Mayor Rodrigo “Rody” Duterte has appealed for calm amid the tension that threatens the passage of the proposed Bangsamoro Basic Law (BBL).

Speaking during the 45th commencement exercises of the Mindanao State University-Iligan Institute of Technology, Duterte last Tuesday expressed concern over statements made earlier by a member of the government peace panel who warned of the possibility of violence breaking out once again should Congress fail to pass the BBL.
