By Phil Stewart WASHINGTON (Reuters) - The United States has decided to allow airstrikes to defend Syrian rebels trained by the U.S. military from any attackers, even if the enemies hail from forces loyal to Syrian President Bashar al-Assad, U.S. officials said on Sunday.

By Valerie Volcovici WASHINGTON (Reuters) - President Barack Obama will unveil on Monday the final version of his plan to tackle greenhouse gases from coal-fired power plants, kicking off what is expected to be a tumultuous legal battle between federal environmental regulators and coal industry supporters. The White House said its revised Clean Power Plan will increase the required cuts in carbon emissions from the power sector, demanding they be slashed 32 percent from 2005 levels by 2030.

A manhunt was under way on Sunday in Tennessee for a parolee suspected of fatally shooting a Memphis police officer who apparently interrupted a drug transaction when he stopped to investigate an illegally parked car, police said. The slain policeman, Sean Bolton, 33, was confronted by the gunman and shot multiple times during a brief scuffle after the officer pulled up to the parked car and shined his spotlight on the vehicle, Memphis police said in a statement. Investigators also recovered a handgun in a field near the shooting scene, the Memphis Commercial Appeal newspaper reported.
