Marathon day for American and Iranian negotiators and experts, Saturday, in Islamabad. Arriving Friday evening in the Pakistani capital, the two delegations immediately began, each on its own side, informal discussions with high-ranking Pakistani officials who reportedly exchanged messages between the two parties to pave the way for formal, face-to-face negotiations, which began Saturday in the early afternoon. Late in the evening, the two delegations completed two successive working sessions and announced a suspension of work that was to continue on Saturday night (which, in this type of situation, opens the way for discussions away from the spotlight) or on Sunday.
