An overwhelming majority of Americans say the United States government should avoid taking any military action in Syria, a new opinion poll has said.

Chinese news agency Xinhua on Friday quoted Gallup's poll conducted on May 28-29 as showing that 68 percent of Americans voiced opposition to U.S. military interference in Syria, compared to 24 percent who favor such action.

At the same time, 58 percent of Americans say they are not optimistic that the crisis in Syria will be solved through economic and diplomatic means, while 27 percent agree that such efforts will succeed, the poll said.

Americans also pay less attention to the crisis in Syria, as the poll finds that less than 49 percent of respondents say they are following news about the crisis in Syria "very" or "somewhat" closely. This is below the historical average of 60 percent for more than 200 news events that Gallup has measured since 1992.

"Thus, Americans seem to have a clear preference for keeping the U.S. army out of the crisis in Syria, given their opposition to such involvement even though they expect that diplomatic efforts will fail to resolve the crisis," Gallup said.

The poll's results come at a time when the U.S. officials and senates continue their interference in Syria's affairs where Republican Senator, John McCain, infiltrated into Syrian territories and announced its support to the armed groups and providing them with more weapons.

Earlier, a poll conducted at the beginning of late May showed that 62 percent of Americans oppose the U.S. military intervention in Syria.
