Nicaraguan Vice President Omar Halleslevens Acevedo on Friday lashed out at Washington's threat to launch armed intervention in the Syria crisis.

The countries that threaten use of force are in no position "to be calling themselves judges of the world," he said in remarks carried by state media.

"The world does not need wars," added the vice president, a retired general and former army chief. "War only increases social problems and the number of deaths."

Domestic conflicts should not be resolved by foreign intervention, and solutions can only be reached through dialogue, consensus and the struggle against hunger and poverty, said Halleslevens.

Meanwhile, UN investigators should be allowed to complete their work, he added.

U.S. President Barack Obama said Friday that he has not made a final decision about a military strike against Syria, but he is considering a limited and narrow action.

The recent flare-up results from an alleged chemical attack last week outside Damascus. The Obama administration said it has "high confidence" that the Syrian government launched the attack, which killed 1,429 people, including 426 children.

The Syrian government has strongly denied the accusation.
