SAN FRANCISCO -- Two pro-Tibet protesters, including one injured in a fall from a climbing rope at the Chinese consulate Wednesday, were charged in federal court Thursday with illegally entering the compound.

Nyendak Wangden, 22, of Suisun City, and Brihannala Morgan, 26, of Oakland, were informed by U.S. Magistrate Bernard Zimmerman that they were accused of forcibly thrusting themselves on a building used for diplomatic purposes.

Zimmerman ruled that the two women could be freed on an unsecured bond and ordered them to return to court on Aug. 20 for a status conference.

Wangden and Morgan are members of Students for a Free Tibet, which was protesting China's human rights record in Tibet.

Wangden, who was hanging from the roof of the consulate on a climbing rope, fell 15 feet to a balcony during the protest and suffered a fractured wrist.

Alma David, a spokeswoman for Students for a Free Tibet, said Wangden's supporters believe the rope was cut.

San Francisco police said Wednesday the incident was under investigation.

Outside of federal court, Wangden's mother, Chime Lhamo, said, "I support my daughter and I am proud of her. She wanted the world to know that the Chinese are illegally occupying Tibet."

The two women dressed in black strung a rope from the roof of the building Wednesday morning, holding banners that said, "Stop the Killing in Tibet" while other protesters from Students for a Free Tibet and the Tibetan Youth Congress waved signs, police said.

Four fire trucks and several police cars blocked the streets surrounding the consulate as Wangden was lowered onto a gurney from an escape ladder.

Wangden was taken to the trauma center at San Francisco General Hospital, according to Mindy Talmidge, a spokeswoman for the San Francisco Fire Department.

Protesters claimed consular personnel on the roof attacked the demonstrators and cut the rope, causing Wangden's fall.

San Francisco police, the State Department and the U.S. attorney's office were conducting a joint investigation of the incident.

"We can't say what the investigation entails," said Sgt. Wilfred Williams.

Chinese consular officials would not comment on whether personnel on the roof engaged with the protesters, but spokesman Defa Tong said that the protesters' "scheme was detected and checked by this consulate."

Consular officials were angry at the lack of protection that allowed the protesters to scale the building.

"The American side bears an unshirkable responsibility for this incident," said Tong.

Police were drawn to the scene when officers patrolling the area saw protesters gathering near the consulate, including three who had chained themselves together in front of the building. They were detained but immediately released.
