Aung San Suu Kyi's opposition party has won 15 out of 16 seats in the first results in Myanmar's historic elections, with a clean sweep so far in its Yangon stronghold, poll officials said Monday.

The NLD's haul includes 12 Yangon electorates in the 323-seat lower house of parliament. It won three regional parliament seats while a fourth went to the army-backed Union Solidarity and Development Party.
