"The ill-wishers of Belarus have proceeded from organising riots to the strangling stage", Lukashenko told Belarusian lawmakers, the Constitutional Commission, and state administrative bodies, as quoted by the state-run news agency Belta.
"They've crossed many red lines, they crossed the boundaries of common sense and human morality", the president concluded.
Lukashenko Slams West for Refusing to Investigate Ryanair Incident
Lukashenko also said on Wednesday that the West refuses to investigate the Ryanair emergency landing in Minsk, Belarus' TV News Agency, part of the Belteleradiocompany state media holding, reported.
"I acted legitimately, I was protecting people, I acted in line with all the international rules. The plane was reversed close to the Belarusian Nuclear Power Plant. What if the NPP safety systems were put on full alert?", Lukashenko went on to say.
Ryanair Bomb Threat Came From Switzerland, Reports Suggest
The message about the threat of an explosion aboard the Ryanair plane, which was forced to make an emergency landing in Minsk, came from Switzerland, Belarus' TV News Agency reported.
On 24 May, the director of the Belarusian Transport Ministry's aviation department said the bomb threat came from Hamas.
However, Hamas spokesman Fawzi Barhoum on Monday denied the group's involvement in the Ryanair incident, saying the organisation does not resort to such methods.
The incident with the Ryanair flight has triggered a wave of criticism from European leaders, who accused the Belarusian authorities of meddling with the European Union's civil aviation and threatened to close Belarusian airspace for international flights. Yet, this is not the first time a plane has been grounded at the request of a third country's authorities. In 2013, the plane of Bolivia's then-President Evo Morales was directed by Austria to make an emergency landing at the behest of the United States, during the hunt for the former National Security Agency contractor Edward Snowden. The whistleblower was not on board.
