UN envoy Ibrahim Gambari held a second meeting with Myanmar's detained democracy icon Aung San Suu Kyi, just hours after his talks with the nation's junta leader.

The two met at a military guesthouse in Yangon, the same place where Gambari met with the Nobel Peace Prize winner for more than an hour on Sunday, the official said.

The 15-minute meeting came immediately upon Gambari's return from Myanmar's remote capital Naypyidaw, where he held talks with junta chief, Than Shwe.

After talking with Aung San Suu Kyi, the envoy headed to the airport in Yangon, where he was expected to board a flight to Singapore, witnesses said.
