MOSCOW, April 30 (Xinhua) -- The Venezuelan crisis should be resolved via a responsible negotiation process without preconditions, the Russian Foreign Ministry said in a statement on Tuesday.

"We call on all sides to renounce the use of violence. It is important to avoid disorder and bloodshed," the statement read.

Instead of seeking to settle political disputes peacefully, the opposition in Venezuela has adopted a course of escalating the conflict, provoking violations of public order and staging clashes with the involvement of the armed forces, it said.

Any actions should be taken exclusively within the confines of the law, in strict conformity with the Constitution and without destructive interference from outside the country, the ministry said.

It asked the international community, including Venezuela's immediate neighbors, to reaffirm commitment to the UN Charter and the norms and principles of international law.

It also urged them to support Venezuela's return to the path of stable and steady development via dialogue between all responsible political forces of that country.

Venezuelan opposition leader Juan Guaido reportedly showed up early Tuesday morning along with some military personnel outside an aviation military base in the east of Caracas. He called on civilians and the military to act against the government and urged President Nicolas Maduro to step down.

Maduro tweeted that military commanders from all regions and defense areas of the country have "expressed their loyalty to the people, the Constitution and the country."
