MEXICO CITY (AP) — Greenpeace Mexico says about 30 of its activists have been briefly detained by Mexico City police after several of them rappelled down the side of a hotel to hang a banner protesting a resort project.

The activists' banner was directed to President Felipe Calderon and read: "Calderon, cancel Cabo Cortes." They were released later Tuesday.

The Cabo Cortes resort is planned for a stretch of the Baja California coast facing the protected Cabo Pulmo coral reef.

Cabo Pulmo is considered a model for recovering degraded reefs, and activists insist runoff and traffic from the resort would harm it.

Calderon's government says that although some permits have been issued, no construction will be allowed unless strict conditions are met.
