Opposition to the US-Israeli war on Iran is increasing in the US, adding pressure on President Donald Trump amid worsening economic concerns.

A new Fox News poll found that 60 percent of Americans now oppose the war, up from 55 percent last month, while 91 percent said the conflict is contributing to economic turmoil.

The survey also showed growing dissatisfaction with the economy, with 77 percent describing economic conditions as “bad”, compared with 73 percent last month and 71 percent a year ago.

Disapproval of Trump’s handling of the economy rose from 56 percent a year ago to 71 percent now.

Overall approval of the president also continued to decline, with 61 percent of respondents saying they disapprove of his performance.
