South African Paralympian and wheelchair racer Ernst van Dyk was at the Boston Marathon when two bomb explosions turned the finish line into a bloody scene of destruction on Monday.
At least three people were killed and many injured when two bombs went off near the Boston Marathon finish line, Boston police said.
Van Dyk was on the other side of the road, directly opposite where the second blast occurred, and saw it happen.
He tweeted: “Was attending a post-race event and the second explosion was right across the street. Was terrible to see it all. Just letting everyone know I'm ok. It's pretty rough out there now and my thoughts are with those who got hurt.”
Two South African athletes were injured in the blasts, authorities say. At total of 28 South Africans registered for the marathon.
No one has been arrested in connection with the blasts but local police confirmed they have identified a suspect.
