CAMBRIDGE, Mass.—Eight children at a church near Harvard University where a French youth choir was holding a concert suffered seizure-like symptoms and were taken to hospitals, possibly the result of fumes from cleaning supplies, officials said.

The symptoms were not life-threatening, the Cambridge Fire Department said in a news release. About 70 other people in attendance at the concert Tuesday evening at St. Paul’s Parish in Harvard Square were not affected.
