HIROSHIMA--A Major League Baseball player who is participating in the Japan All-Star Series has apologized for uploading footage of the Hiroshima atomic bomb site that showed a bomb icon flying in the sky.

Boston Red Sox pitcher Hector Velazquez, 29, added the icon and the words "Atomic bomb!" to scenes he shot in Hiroshima, including the Atomic Bomb Dome.

The Mexican-born player apologized at Mazda Stadium here on Nov. 13, saying he did not intend for the video, uploaded on YouTube, to be offensive.

He said he made a mistake in trying to introduce the city, which was devastated by a U.S. atomic bombing 73 years ago, to his friends in his home country.

Velazquez is visiting Japan as a member of the MLB all-star team, which is playing an exhibition series against a Nippon Professional Baseball all-star team. The two teams played in Hiroshima on Nov. 13.

The Japan All-Star Series organizers said they plan no punitive measures against the player because he has deeply apologized.

In a statement, the Yomiuri Shimbun Group headquarters, one of the organizers, also offered apologies.

"His actions are unacceptable as they trample on the feelings of many people, particularly atomic bomb victims and Hiroshima residents," the statement read. "We will urge MLB to take strict measures to prevent a recurrence."
