HOUSTON (AP) - Houston’s mayor and others say they'll work to provide aid for residents whose homes were damaged after a massive explosion at a warehouse that killed two workers and injured 20 others. Mayor Sylvester Turner on Saturday walked through impacted neighborhoods and spoke with residents who were cleaning up after Friday’s explosion. Dozens of volunteers helped residents board up windows and put up tarps on damaged roofs. The cause of the blast at a business that makes valves and provides thermal-spray coatings for equipment is under investigation. Cleanup and repair efforts continued Sunday.
