The Southeast Asian country has been in turmoil since the military toppled democracy figurehead Aung San Suu Kyi's civilian government, alleging massive fraud during elections her party won in 2020.

A junta-imposed state of emergency is due to expire at the end of January, after which the constitution states that authorities must set in motion plans to hold fresh elections.

The military was widely expected to announce Wednesday that it would prepare for the polls.

But a junta-stacked National Defence and Security Council met Tuesday to discuss the state of the nation and concluded it "has not returned to normalcy yet", the military's information team said in a statement.

Junta opponents, including anti-coup "People's Defence Forces" (PDF) and a shadow government dominated by lawmakers from Suu Kyi's party, had tried to seize "state power by means of unrest and violence" the statement added.

Those "who want utter devastation of the state are continuing their activities", it said.

The "necessary announcement will be released" on Wednesday, it added, without giving details.

Junta chief Min Aung Hlaing has previously said elections could only be held when the country was "peaceful and stable".

Under the military-authored 2008 constitution, the president in coordination with the Defence and Security Council can extend a state of emergency for six months upon a request from the head of the military.

Former civilian president and close Suu Kyi ally Win Myint has been detained since the coup and jailed on a clutch of charges by a closed junta court.

Acting President U Myint Swe attended the Tuesday meeting, the military said.

"We still do not know the decision of the meeting," a military source told AFP, requesting anonymity.

"We have been told to be on standby for possible attacks by PDF in coming days in the regions. We have no black-and-white instruction.

"Whether the state of emergency situation is continued or not, we will be in the military barracks. We also want the situation to return to normalcy."

Last week the junta gave existing and aspiring political parties two months to re-register under a strict new electoral law, in a sign it was planning fresh polls for this year.

But with armed resistance raging across swathes of the country, analysts say people in many areas will be unlikely to vote -- and run the risk of reprisals if they do.

A United Nations special envoy said Tuesday that elections would "fuel greater violence, prolong the conflict and make the return to democracy and stability more difficult".
