Boston is a city on high alert after two bombs exploded at the finish line of the Boston Marathon. At last report, two people were killed and dozens wounded.

There may also be more bombs to deal with.

The two explosions went off in quick succession at the finish line of Monday's Boston Marathon. The first blast was followed by a cloud of white smoke, and just seconds later another explosion, and more white smoke.

Complete chaos ensued, with several people running for cover and crying. Debris and blood covered the area. There were immediate reports of mass casualties.

Police and emergency personnel rushed to the scene to cordon off the area and attend to the wounded. Early pictures showed numerous victims being transported by wheel chairs and on stretchers to local hospitals.

The Boston Marathon is one of the biggest and premiere races in the country, with tens of thousands participating. The explosions came hours after the winners had crossed the finish line.

A number of Coastal Bend residents made there way up to Boston for the marathon, including members of the local running group called the Roadrunners. Among the members of that group were, Donnie Patterson, a cross-country coach at Incarnate Word Academy, and his wife. They had just finished the race prior to the explosions.

At last check, the group from Corpus Christi appeared to be okay and out of harms way.
