WASHINGTON – Secretary of State Hillary Rodham Clinton was admitted to a New York hospital Sunday after the discovery of a blood clot stemming from the concussion she sustained earlier this month.

Clinton’s doctors discovered the clot Sunday while performing a follow-up exam, her spokesman, Philippe Reines, said. He would not elaborate on the location of the clot but said Clinton is being treated with anti-coagulants and would remain at New York-Presbyterian Hospital for at least the next 48 hours so doctors can monitor the medication.

Clinton, 65, fell and suffered a concussion while at home alone in mid-December as she recovered from a stomach virus that left her severely dehydrated.

Landlord accused of killing teen tenants

A 74-year-old Maine man was charged in the shooting deaths of two tenants inside an apartment he rented out at his home, possibly over a dispute about parking, state police said Sunday.

James Pak was arrested at about 10 p.m. Saturday after a standoff at his home in Biddeford, about 15 miles south of Portland, police said. He is charged with two counts of murder in the deaths of Derrick Thompson, 19, and Thompson’s girlfriend, 18-year-old Alivia Welch.

Before the shootings, Biddeford police were called to Pak’s home regarding a dispute between Pak and his tenants over their cars being parked in his driveway during the snowstorm, said state police spokesman Steve McCausland. Biddeford banned street parking during the night so city crews could plow the streets.

Ailing Chavez faces new complications

Hugo Chavez has suffered “new complications” since his cancer surgery in Cuba, his vice president said Sunday, describing the Venezuelan leader’s condition as delicate.

Vice President Nicolas Maduro spoke with a solemn expression in a televised address from Havana, saying he had spoken with Chavez and that the president sent greetings to his homeland.

The vice president’s comments suggest an increasingly difficult fight for the ailing president. The Venezuelan leader has not been seen or heard from since undergoing his fourth cancer-related surgery Dec. 11, and government officials have said he might not return in time for his scheduled Jan. 10 inauguration for a new six-year term.

African Union leader tries to quell unrest

The leader of the African Union, Benin President Thomas Boni Yayi, has proposed a government of national unity to resolve the rebel conflict in Central African Republic.

Boni Yayi arrived Sunday in the capital of Bangui to try to find a negotiated resolution to the country’s crisis. He met with President Francois Bozize and then made an appeal to the rebels.

The landlocked nation of 4.4 million people remains one of the poorest countries in the world despite its wealth of gold, diamonds, timber and uranium.

The rebels say they are fighting because of their “thirst for justice, for peace, for security and for economic development of the people of Central African Republic.”

‘Lady of the Cells’ dies in Italy at 103

Rita Levi-Montalcini, a biologist who conducted underground research in defiance of Fascist persecution and went on to win a Nobel Prize for helping unlock the mysteries of the cell, died at her home in Rome on Sunday. She was 103 and had worked well into her final years.

Italy’s so-called “Lady of the Cells,” a Jew who lived through anti-Semitic discrimination and the Nazi invasion, shared the Nobel medicine prize in 1986 with American biochemist Stanley Cohen for their groundbreaking research. Her research increased the understanding of many conditions, including tumors, developmental malformations, and senile dementia.

Five elephants killed by train in India

A passenger train has plowed into and killed five elephants of a herd crossing railroad tracks in eastern India.

R.N. Mohapatra, a railroad spokesman, says the train struck the animals early Sunday in the Rambha forest area, about 110 miles south of Bhubaneshwar, the capital of Orissa state.

J.D. Sharma, chief conservator of the state’s wildlife department, accused the railroad authorities of ignoring his department’s warning that trains should slow down because a herd of elephants was moving in the area.
