YANGON — Myanmar leader Aung San Suu Kyi has been detained by the military along with President Win Myint, a spokesman for the ruling National League for Democracy said on Monday.

After the NLD decisively won the November general election, the military and the main opposition party that it backs disputed the results. 

Myanmar's state broadcaster said on Monday it has been unable to provide regular broadcasts on TV or radio, in what could be a sign that the military is disrupting airwaves.

NLD spokesman Myo Nyunt said that among those detained were other senior party officials, adding he also expected to be detained soon.

Parliament was supposed to convene on Monday for the first time since the November 8 general election, and an NLD-led government was supposed to be launched for a second time.

Reuters news agency reported the presence of military vehicles and soldiers outside City Hall in the largest city Yangon. Internet and phone services were reportedly disrupted in the capital Naypyitaw and Yangon.

In the election, the NLD won 83 per cent of the votes, capturing 396 of the 476 seats up for grabs. The military-backed Union Solidarity and Development Party secured just 33 seats, down from slightly over 40 in the last election in 2015.

The military and opposition party went on to allege massive election fraud. When they called for a special session of parliament to discuss the matter, the parliament leadership rejected it.

On Wednesday, Military chief Senior Gen Min Aung Hlaing referred to the possibility of abolishing the current constitution, raising political tensions in the country.

The parliament has a combined 664 seats in the upper and lower houses, with 25 per cent of the total, or 166 seats, set aside for military appointees.

In the 2015 general election, the NLD won a landslide, bagging 390 of the 491 seats contested, bringing Suu Kyi and her party to power for the first time the following year. KYODO
