Hundreds raced in Saturday’s Gaza Solidarity 5K at Rock Creek Park, raising more than $80,000 for vital social services in the Gaza Strip. Cases of post-traumatic stress disorder among children have doubled since last November’s conflict with Israel, said Abby Smardon, executive director of the non-profit American Friends of UNRWA.

“It’s not often that people in DC can really show their support for the children of Gaza,” she said, “but this is a great way for them to do it.”

The organization’s second annual solidarity race was twice the size of last year’s, with more than 400 registered runners.
