DENVER - Thirteen anti-abortion activists, including Operation Rescue founder Randall Terry, were arrested after blocking a security gate near the site of the Democratic National Convention.

Police three times asked about 35 protesters to leave before making the 13 arrests.

The protesters were being bused to a detention facility.

Earlier today, anti-abortion activists unfurled a huge sign on a mesa west of Denver equating the Democratic National Convention with abortion, but later removed it at the request of authorities.
