Dhaka, Bangladesh (CNN) — A fire ripped through a clothing factory near the Bangladesh capital of Dhaka, killing at least 117 people and sending workers jumping out of the multistory building.

At least 200 people were injured as they rushed to get out of the factory in Ashulia, police said.

Firefighters battled to contain the raging blaze that started Saturday night on the first floor of the nine-story building and spread to other floors, leaving hundreds of workers, mostly women, trapped.

Officials said some 2,000 people were working in the factory as the fire began, but it was unclear how many had been rescued.

The fire department said rescue operations have been very difficult because the factory was packed with fabrics, yarn and cotton, the fire department said. It said the death toll might rise because firefighters could not enter some floors of the building.

WELD COUNTY, CO – As part of its Smart Energy Plan, Weld County is in the process of converting its government fleet vehicles to natural gas vehicles – both Compressed Natural Gas (CNG) and Liquefied Natural Gas (LNG). On Wednesday, three of the county’s four LNG trucks were on hand at the County Administration Building.

“We are excited about the conversion,” said Commissioner Barbara Kirkmeyer. “Natural gas vehicles are more efficient and require less maintenance which equates to lower costs for the county.”

The county received its first LNG truck in July 2012 and has already realized a 22% reduction in fuel costs which will equate to approximately $25,000 in fuel savings per year per truck. “Over the life of the truck, we are expecting to save an estimated $100,000 on fuel alone – that’s per truck,” said Jay McDonald, Division Supervisor for Weld County’s Department of Public Works.
