Anti-abortion activists rallying on Boston Common clashed with counterprotesters Sunday afternoon, resulting in seven arrests.

Chanting and carrying signs opposing new restrictive abortion laws in several states, about 100 counterprotesters booed and jeered at the more than 100 anti-abortion activists as they gathered.

At the Parkman Bandstand, anti-abortion activists played music, including Christian rock and church hymns, to drown out the opposition and held signs asking people to “pray to end abortion.’’ Some dropped to their knees, eyes closed, to pray.
