Cameras were rolling as the explosions erupted near the main grandstand where spectators had gathered.
The remaining runners were diverted and the race canceled as emergency crews rushed in.

Injuries are severe. Some of the victims have reportedly lost limbs.

WAUSAU - The Wausau School District will use a large grant to renovate the school's planetarium. The current Wausau School District planetarium was built in the late 1960s, and it needs some upgrades.
The school just received a $230 thousand grant to complete the project. It is expected to take two years to complete.
"The first year is running the software, showing it, using it in our classrooms in our curriculum," said planetarium director Chris Janssen. "Finding out, 'is this going to work 100% of the time?' Year two then is going to be the actual, physical structure upgrades. The dome will get replaced, seats, cement contractors will come in and tilt the floor and so-on."
The planetarium can hold 54 people, and organizers are hoping to keep it that way.
"For curricular needs, when you have two classes come in, and the classes are about 26 kids each, you gotta have that sweet spot of about 50-54 seats. When you tilt the floor, you lose some space, so I really want to try and keep it at about 50 seats."

RHINELANDER - A Norther Lights Tour scientist explained Rhinelander's role in potato breeding and genetic studies on Wednesday night.
Every year about 50,000 varieties of potato are tested to see if they could be commercially sold.
Only about one in a 100,000 will become a named potato variety.
"The Rhinelander agriculture research station on Highway C is really where that process starts by making the cross pollination, raising those plants for the first time in a greenhouse and then evaluating them in the fields there for a couple years," said UW- Madison Assistant Professor of Horticulture Jeffry Endelman.
MADISON - A convicted sex offender from Rhinelander can keep pictures of children he cut out of magazines.
A state appeals court dismissed new charges against Albert Chagnon Thursday.
Prosecutors charged the 33-year-old last year with 23 counts of intentionally photographing a minor without consent. Chagnon was about to be released from prison when a guard discovered a notebook in his pants containing photographs of fully-clothed young girls cut out of magazines or newspapers, including the Lakeland Times.
Chagnon argued that the charges should be dismissed because he didn't take the photographs. The 4th District Court of Appeals agreed with him Thursday, saying state law doesn't cover Chagnon's conduct.
