TOKYO (CNN) - Japan will lobby a dozen members of the International Whaling Commission at a meeting Monday to support its much-criticized Antarctic whaling program - just three days before all members of the commission meet in London to discuss reaching an agreement on whale conservation rules.

Japan's Ministry of Foreign Affairs and the nation's Fisheries Agency will make their case to officials from Angola, Eritrea, Congo, Guinea, Ghana, Malawi, Tanzania, Palau, Micronesia, Cambodia, Laos and Vanuatu, ministry spokeswoman Eri Okabe told CNN. Several of the countries are new to the 78-member whaling commission.

Two months ago, Japan "temporarily halted" its plan for a humpback whale hunt in the seas near Antarctica as what it said was a gesture to enhance the dialogue at the International Whaling Commission, which remains torn over whaling.

MIAMI (CNN) - Police were called to Miami Edison Senior High School after a student protest became unruly Friday, officials said.

Quintin Taylor, a spokesman for the Miami-Dade School Board, said "a couple of hundred" students were involved in the protest, which began during lunch hour in an open patio next to the cafeteria.

Minor injuries were reported among police and students, and video from the scene showed several students being led away as if under arrest.

Students told television station WSVN they were angry that the principal put a student in a "choke hold" Thursday.

LAS VEGAS (CNN) - Two tests have confirmed a substance found in a Las Vegas extended-stay hotel room is the deadly poison ricin, and a man who was staying there has been hospitalized for more than two weeks and is currently in critical condition, police said Friday.

The man, whose name was not released, summoned authorities Feb. 14 and asked to be transported to a hospital because of difficulty breathing, Kathy Suey, deputy chief of the Las Vegas Metropolitan Police Department, told reporters.

But police were not aware of the ricin's existence until Thursday, when a second man, who identified himself as a relative of the victim, went to the Extended Stay America room to clear the victim's possessions out and found the substance. That man brought the poison, which was in vials in a plastic bag, to the manager's office, and police were notified.

LAS VEGAS (CNN) - A second test confirms that ricin was in a bag found in a hotel room in Las Vegas, Las Vegas police said Friday.

Kathy Suey, deputy chief of the Metropolitan Police Department, said the test was done locally. The preliminary test also showed ricin.

LAS VEGAS (CNN) - A previous guest of a Las Vegas hotel room where ricin has been found is in critical condition at a hospital, where he has been since Feb. 14, said Kathy Suey, deputy chief of the Las Vegas Metropolitan Police Department.

A different person reported the suspicious bag of ricin to authorities, she said.

(CNN) - The discovery of a small amount of what authorities believe to be the deadly poison ricin in a Las Vegas hotel room "does not appear to be related to terrorism," FBI spokesman Richard Kolko said Friday.

A report from the the Washington Regional Threat and Analysis Center said the FBI considers the discovery "criminal in nature."

Preliminary tests show the substance is ricin, but other tests to confirm that are being done by the Centers for Disease Control and Prevention (CDC) in Atlanta. Results are expected later Friday.

ATLANTA (CNN) - A man who was arrested in suburban Atlanta after a months-long, three-nation manhunt will be deported from the United States and returned to New Zealand to face murder charges in the death of his wife, authorities told CNN Friday.

Nai Yin Xue, believed to be in his early 50s, was arrested in Chamblee, Ga., on Thursday after residents of an apartment complex recognized him from a Chinese-language newspaper, called police and detained him until officers arrived, police said. He is accused of killing his wife, Anan Liu, 27, and stuffing her body in the trunk of a car outside the couple's Auckland, New Zealand, home last September.

Days later, authorities said, he abandoned the couple's 3-year-old daughter at a Melbourne, Australia, train station. The child became known internationally as "Pumpkin" because of a label in the sweater she was wearing. Authorities attempting to contact her parents discovered her mother's body.

ISLAMABAD, Pakistan (CNN) - A suicide attack on the funeral Friday of a district superintendent of police - killed earlier in the day in a separate attack - killed at least 11 people and injured 50 in northwest Pakistan, Interior Ministry spokesman Javed Iqbal Cheema told CNN.

Other reports put the death toll much higher. A police source at the Swat province's special branch of police said there were 30 dead and 50 to 55 people injured in the blast, which occurred in Minora, Swat's capital.

He said the attack took place on a funeral procession, and caused an electricity blackout, which made it difficult to ascertain exact casualty numbers amid the confusion.

NEW YORK (CNNMoney.com) - Two Federal Reserve officials said Friday that the housing market could damage the economy even more severely than it has already if measures are not taken to correct it.

In speeches at the U.S. Monetary Policy Forum in New York, Eric Rosengren, president of the Federal Reserve Bank of Boston, and Frederic Mishkin, a member of the Federal Reserve board of governors, spoke about the critical nature of the housing market crisis.

"Further declines in housing prices could depress residential investment, reduce consumer spending, generate elevated foreclosures, and contribute to financial instability," Rosengren said. "Taking appropriate monetary, regulatory, and fiscal actions to mitigate this risk seems prudent."

WASHINGTON (CNN) - Eight members of the military who objected to taking a mandatory anthrax vaccine lost another round in federal court Friday.

A District of Columbia federal judge dismissed a lawsuit from service members who claim the federal government is forcing them to take an unproven and potentially ineffective drug to stop the deadly bacteria.

The ruling was the latest in a long-running legal fight over the vaccine.
