Oklahoma tornadoes kill at least four people and leave dozens injured

Governor issues state of emergency for 12 counties as authorities confirm a four-month-old baby was among the dead in Holdenville

At least four people, including a baby, were killed after a series of tornadoes struck Oklahoma on Saturday, amid a weekend of extreme weather that left dozens injured and a trail of destruction across the midwest.

Local authorities confirmed that a four-month-old infant was among the two people dead in Holdenville - one of the hardest hit towns in Oklahoma, located 80 miles south-east of Oklahoma City - where about 20 tornadoes hit late Saturday, leveling buildings and ripping off roofs. The victims have not been named, but at least four others were injured as the tornado left a path of devastation through the town of around 6,000 people.
