The Obama administration's increasing use of unmanned drone strikes to kill terror suspects is widely opposed around the world, according to a Pew Research Center survey on the U.S. image abroad.

In 17 out of 21 countries surveyed, more than half of the people disapproved of U.S. drone attacks targeting extremist leaders and groups in nations such as Pakistan, Yemen and Somalia, Pew said Wednesday.

But in the United States, a majority, or 62 percent, approved the drone campaign, making American public opinion the clear exception.

"There remains a widespread perception that the U.S. acts unilaterally and does not consider the interests of other countries," the study authors said, especially in predominantly Muslim nations, where American anti-terrorism efforts are "still widely unpopular."

The White House declined to comment on the report. The Obama administration considers drone strikes
