Texas energy freeze stretches to sixth day, raises Mexico's ire

Texas’s freeze entered a sixth day on Thursday, as the largest energy-producing State in the United States grappled with massive refining outages and oil and gas shut-ins that rippled beyond its borders into neighbouring Mexico. The cold snap, which has killed at least 21 people and knocked out power to more than 4 million people in Texas, is not expected to let up until this weekend. The deep freeze has shut in about one-fifth of the nation's refining capacity and closed oil and natural gas production across the State.
