Two women and three children have been taken to hospital following a crash on the M5 motorway.
The three car pileup on the northbound carriage near to the Tewkesbury junction (nine) took place just before 11.30am this morning.
Traffic is said to be queued back to Brockworth (junction 11A) as police closed part of the northbound road and re-directed traffic.
A dog was also said to have been involved in the crash, but is thought to have been uninjured.
None of the women are thought to have been seriously injured and the kids were said to have been taken to hospital as a precautionary measure.
A Vauxhall Zafira, a BMW estate and an Audi estate were all said to be involved in the smash.
Gloucestershire Police said recovery for the cars was on the way.
Other reports of a seven car pile-up came in from emergency service.
But a spokesman for Gloucestershire Constabulary confirmed only the three cars were left with vehicle damage, following the crash.
She confirmed no one was believed to have been seriously injured.
Drivers have been warned to expect significant congestion and are being advised to avoid the area and find another route.
The road remained open to those traveling south.
Just before 2pm all three lanes of the northbound road re-opened as the smashed up cars lay on the hard shoulder.
But traffic is expected to be heavy for the rest of the afternoon as many return home from the Christmas break.
