GLENPOOL, Okla. (AP) - Authorities say more than a dozen people were injured in a two-vehicle wreck in Okmulgee County on Sunday night.

The Oklahoma Highway Patrol says a van carrying members of the faith-based recovery group Teen Challenge of Oklahoma was having mechanical issues and stalled on U.S. 75. Tulsa television station KOTV reports (http://bit.ly/1RibeKh ) that a northbound truck rear-ended the stalled van at about 10 p.m. Sunday.

The highway patrol says 14 people were taken to hospitals with injuries, including two who were transported by medical helicopter.

Authorities say the wreck also sparked a small grassfire, but it was brought under control.
