Satellite image provider DigitalGlobe Inc. has released photos that it says show Syrian army tanks and other armored vehicles in the city of Homs.
DigitalGlobe says the images were taken Friday in the late morning Syrian time.
Stephen Wood, director of DigitalGlobe's analysis center, says some of the photos show armored vehicles near apartment buildings.
The Syrian government has been trying to suppress an 11-month-old uprising.
Wood says the photos were taken by DigitalGlobe's WorldView 2 satellite from about 480 miles above the Earth.
DigitalGlobe is based in Longmont, Colo., and sells satellite imagery and analysis to clients that include the U.S. military, emergency response agencies and private companies.
The company has three orbiting satellites, and a fourth is under construction.
