LI chief Mangal Bagh on Tuesday refused to provide monetary and other guarantees to ensure writ of the state in Khyber Agency. 'I can give you my word, but I cannot give men as guarantors,' he told a tribal jirga that met him in Tirah Valley. 'In tribal society, words matter. I will honour my word,' Bagh told the negotiators. Jirga leader Amal Gul Afridi said that he was 'satisfied' with the talks. 'A promise is stronger than a guarantee (in tribal system),' he told Daily Times upon returning to Peshawar.
