   MOSCOW (AP) — The organizers of the World Athletics Championship in Moscow say they will beef up security in the wake of deadly explosions at the finish line of the Boston Marathon.

   The August 10 to 18 event is seen as a dress rehearsal for the 2014 Winter Games in Russia's Black Sea resort of Sochi.

   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.
