Attorneys for an inmate convicted in a prison guard's death are asking the U.S. Supreme Court to halt his Thursday evening execution.

Robert Pruett's lawyers want justices to review whether lower courts properly denied a federal civil rights lawsuit that sought additional DNA testing in the case. They are also questioning whether a prisoner who claims actual innocence, as Pruett does, can be put to death.

If the execution is carried out Thursday, Pruett would be the sixth prisoner executed this year in Texas, which carries out the death penalty more than any other state. Texas put seven inmates to death last year. His execution would be the 20th nationally, matching the U.S. total for all of 2016.

Pruett avoided execution in April 2015, when a state judge halted his punishment just hours before he could have been taken to the death chamber. His lawyers had convinced the judge that new DNA tests needed to be conducted on the steel rod used to stab the 37-year-old Nagle.

The new tests showed no DNA on the tape but uncovered DNA on the rod from an unknown female who authorities said likely handled the shank during the appeals process after the original tests in 2002.

In June, Pruett's execution was rescheduled for October. Pruett's attorneys then unsuccessfully sought more DNA testing and filed a federal civil rights lawsuit in August, arguing Pruett had been denied due process. The 5th U.S. Circuit Court of Appeals rejected the lawsuit last week, and Pruett's attorneys appealed to the U.S. Supreme Court on Tuesday.

North Carolina's highest court is reviewing whether justice means the death penalty for a survivor of El Salvador's blood-soaked civil war of the 1980s who strangled and then decapitated his estranged wife.

The state's Supreme Court hears oral arguments Monday on whether the state can execute 41-year-old Juan Carlos Rodriguez of Winston-Salem for the 2010 murder of his wife, Maria. The high court automatically reviews death cases.

North Carolina is rare among southern states in that it hasn't had an execution in more than a decade because of various legal challenges. While the state has continued to suffer 500 to 600 murders a year, prosecutors have sought the death penalty only a handful of times each year and juries have condemned killers in only a fraction of those cases.

Rodriguez's children told investigators their father beat and bloodied Maria Rodriguez after she told them she was leaving in November 2010. He tossed the woman's still-breathing body over his shoulder, placed her in his vehicle, and said he was taking her to a hospital. Maria's body and severed head were found at different locations three weeks later, after Juan was already jailed for her kidnapping.

Justices are holding hearings in the case for the second time in almost exactly a year. Monday's hearing comes after the U.S. Supreme Court ruled this spring that states needed to use current medical standards in deciding whether a killer is so mentally disabled he can't be executed. The U.S. constitution bans "cruel and unusual punishments," and that has been interpreted to prohibit executing people with severe mental shortcomings.

Rodriguez's IQ was estimated several times at below 70, a threshold for significantly impaired intellectual functioning. But accused killers in North Carolina also must show significant inability to adapt to daily life and that their mental handicaps were evident before adulthood.

Kenya's Supreme Court is delivering its full judgment on why it annulled President Uhuru Kenyatta's re-election in August.

The court annulled Kenyatta's victory in the August 8 election saying there were irregularities and illegalities, in response to opposition leader Raila Odinga's petition challenging the official results that Kenyatta won with 54 percent of the vote. The electoral commission has set Oct. 17 as the date for a fresh election. Kenya's Chief Justice David Maraga said Tuesday that since the September 1 judgment nullifying the election results, there have been attempts to intimidate judges.

Kenyatta has called the Supreme Court judges "crooks" and warned of unspecified action against the judiciary if he is re-elected next month. Kenyatta's supporters demonstrated outside the Supreme Court Tuesday ahead of the full judgment on Wednesday.

A Palestinian court has extended the detention of a prominent activist who criticized the autonomy government of President Mahmoud Abbas.

Farid al-Atrash, the lawyer of Issa Amro, said Thursday that the court had extended his client's detention for four days.

He says Amro is being held under a recent edict that allows the government to crack down on social media critics. In a Facebook post, Amro criticized the detention of a local journalist who called for Abbas' detention.

"This is a black day in the history of the Palestinian judicial system and for Palestinian freedom of expression," al-Atrash said.

Amro was detained on Monday and has been on a hunger strike since then. Amro, 35, also faces charges in an Israeli military court. His trial is to resume in October.

Descendants of black slaves, known as freedmen, who were once owned by members of the Cherokee Nation have a right to tribal citizenship under a ruling handed down by a federal court in Washington, D.C.

U.S. District Judge Thomas Hogan ruled Wednesday in a long-standing dispute between the Cherokee Freedmen and the second largest tribe in the United States.

Freedmen have long argued that the Treaty of 1866, signed between the U.S. government and the Tahlequah, Oklahoma-based Cherokees, gave them and their descendants "all the rights of native Cherokees." There are around 3,000 freedmen descendants today.

But Cherokee leaders have argued the tribe has the fundamental right to determine its citizens, and in 2007 more than three-fourths of Cherokee voters approved an amendment to remove the Freedmen from tribal rolls.

Tom Clancy's widow wants a court to rule that the author's estate is the exclusive owner of the rights to his famous character Jack Ryan.

News media outlets report that Alexandra Clancy's lawsuit says that the author's estate should be the sole beneficiary of any posthumous books featuring the character who was first introduced in "The Hunt for Red October."

Alexandra Clancy is suing the personal representative of Clancy's estate, J.W. Thompson Webb, for allowing other entities to profit from posthumous book revenues. Clancy's first wife, Wanda King, is a partial owner of those other entities.

The lawsuit says: "Tom Clancy made Jack Ryan; and in a sense, Jack Ryan made Tom Clancy."

The lawsuit was filed in the Circuit Court in Baltimore. Tom Clancy died in 2013.
