Emergency services are searching for survivors after a blast at a fertiliser plant in the US state of Texas killed between five and 15 people.

More than 160 people were injured and dozens of buildings were destroyed in the town of West, near Waco.

Three or four volunteer firefighters are among the missing after the explosion, which produced a tremor equivalent to a small earthquake.

Emergency services officials said ammonia may have caused the explosion.
