New York, Feb 27 (IANS): Bags are prohibited from this year's Boston Marathon for security concern following last year's deadly bombing, authorities announced.

Marathon runners typically are allowed to bring bags or backpacks to keep personal items.

But this year, runners will not be allowed to bring backpacks or bags, which will also not be allowed in certain areas near the start or finish line, or along the 26.2-mile course, Xinhua qupoted the Boston Athletic Association as saying Wednesday.

Runners will be given a chance to check gear on Boston Common on the morning of the marathon to allow them to have a change of clothing at the end of the race.

The athletic association said it will provide clear plastic bags for that purpose.

Runners were told they cannot bring backpacks or any similar item carried over the shoulder or handbags of any size.

Twin bombs placed in backpacks near the 2013 finish line killed three people and injured more than 260. Prosecutors say two spectators were responsible.
