The R-Sport news agency on Tuesday quoted Valentin Balakhnichev, president of the Russian Athletics Federation, as saying that the organizers "will draw conclusions" from the Boston bombings.
Balakhnichev said the security standards they adhere to are high but the organizers "will take tougher measures" to ensure security.
