On Saturday, a drone strike in Yemen killed at least 10 suspected al Qaeda militants but also inadvertently resulted in the deaths of three civilian day laborers, a high-level Yemeni government official said.
The United States is the only country known to have conducted drone strikes in Yemen. As a rule, U.S. officials don't comment on these strikes.
