Ban met Saturday with Senior Gen. Than Shwe for a second inconclusive round of talks. Ban told reporters he is sorry to report it is "not possible" for him to see the jailed Nobel Peace Prize winner. The UN chief earlier described his two-day trip to Myanmar as "a very tough mission" to try to win freedom for Suu Kyi.

Suu Kyi is on trial for allegedly violating her lengthy house arrest and could face five years in prison in a case that has sparked global outrage.
