[EX Q]: Abuja, Nigeria (CNN) -- More than 70 members of the Islamist extremist group Boko Haram have been killed during a Nigerian military operation in the northeastern state of Borno, an Army spokesman told CNN on Friday. The military "remains on the offensive," according to Brig. Gen. Ibrahim Attahiru, who said the operation started Thursday and continued into the next day. Who are the world's 10 most dangerous terrorists? This wasn't the only clash between Boko Haram and Nigerian troops of late. Suspected members of the extremist group around 5:30 p.m. Wednesday (12:30 p.m. ET) attacked a military checkpoint in Damaturu, Nigeria's Joint Task Force reported in a statement. Also in northern Nigeria, Damaturu is the capital of Yobe state. Special operations troops responded, waging "a fierce encounter with the terrorists in various parts of Damaturu ... for several hours," according to the Joint Task Force. By the time that fighting was over, 21 suspected Boko Haram fighters were dead, the government group reported. Three vehicles were recovered, as were assault rifles, a rocket-propelled grenade, improvised explosive devices and 709 rounds of ammunition. The military did not provide any information on its casualties. "Law abiding citizens are enjoined to remain calm as the 3 Division Special Operation Battalion is on top of the situation," the Joint Task Force said, noting a 24-hour curfew was imposed throughout the state. "Any credible information should be passed promptly to security agencies for necessary action." Last May, President Goodluck Jonathan put three states in the region under a state of emergency, giving Nigerian forces wide latitude in fighting the group, which human rights organizations say has killed more than 3,000 people since 2009. Boko Haram, which means "Western education is sacrilege" in the Hausa-Fulani language, seeks to impose a strict version of Sharia law across northeastern Nigeria, if not the entire country. The group has attacked various targets in the West African nation since its formation in the late 1990s, according to the U.S. National Counterterrorism Center, including killing and kidnapping Westerners, and bombing schools and churches. Hundreds of its members, including its leader Mohammed Yusuf, died in July 2009 clashes with government forces. But the group did not stay down for long, and has remained an active and violent force in Nigeria. In August, its militants allegedly went into a mosque in Borno state and killed 44 worshipers. The group released a video boasting that it was growing stronger. Opinion: Should U.S. fear Boko Haram? CNN's Vlad Duthiers reported from Nigeria, CNN's Greg Botelho wrote this story from Atlanta. CNN's Nana Karikari-apau contributed to this report.

[EX Q]: (CNN) -- Florida's effort to reunite families with the remains of their relatives believed to be buried on the grounds of a now-defunct reform school is being challenged by county officials. Commissioners in Jackson County, Florida, have filed a court motion to thwart the efforts of the state attorney general, who filed a motion earlier this month seeking the excavation of nameless graves on the grounds of the Dozier School for Boys in the Florida panhandle town of Marianna. It's yet another chapter in the long, sordid past of the reform school. Inmates sent there have told tales of brutal beatings, sexual assaults, murder and boys who simply disappeared. The graves, marked only by white tubular steel crosses, have been there since the early 1900s. Even though the graves are on state property, the county objects to the proposed exhumations because it said it has not been determined who will pay for the efforts of the county medical examiner, who would be directing the effort. In its circuit court filing, the county also said that notice has not been made to the family members of those who died. Glen Varnadoe has been one of the leaders in the effort to have the graves exhumed. He said his father and his uncle were sent to the reform school in 1934 after they allegedly stole a typewriter. Mystery surrounds graves at boys reform school . Thirty days later, he said, his uncle, Thomas Varnadoe, was buried on school property. Varnadoe said his father told him that they were regularly beaten during their time at the school. One night, his father said, he was awakened by guards who brought him to a freshly dug grave site in the woods, where school administrators told him that his brother had just been buried. He was only told that his brother died from pneumonia. Varnadoe said he simply wants his uncle's remains so he can bury him properly. And he said he is willing to file a civil action against Jackson County to make that happen. "I'm angry, and I'm aggravated," Varnadoe said. "I think they're going to be in for a tough fight." "Look how they buried these people," he said. "If they want me to go away, then point me to Thomas Varnadoe's grave, and I'll have him disinterred and moved, and I'll leave these people alone." CNN's calls to the Jackson County Commission went unanswered. For years, stories and allegations of beatings, torture and murder have surrounded the century-old school. State authorities have said in the past that there were 31 burial sites at the school, and a 2009 state investigation found no wrongdoing in connection with those deaths. The case of the unnamed, unmarked graves has gotten a large amount of public attention in recent months, after a research project by the University of South Florida uncovered evidence that about 50 bodies are buried beneath and around the 31 crosses that make up the cemetery in the middle of the woods on the school's property. In the wake of the university's findings, U.S. Sen. Bill Nelson, D-Florida, asked the Department of Justice to investigate. Earlier this week, Nelson toured the cemetery site. "This is something that may be another part of our sordid past. This place was set up in the early 1900s and it was a different era back then when it came to civil rights," Nelson said. The mystery surrounding the graves first made headlines in 2008 when Florida's then-governor, Charlie Crist, ordered an investigation after a group of men, known as "the White House Boys," came forward with stories of how they were beaten with leather straps by school administrators inside a small, white building on school property. The Florida Department of Law Enforcement's 2009 report said most of the 31 boys known to have been buried in the school's cemetery were killed in a 1914 fire at the facility, while others died in a 1918 flu outbreak. At the time, the law enforcement agency said it could not determine where another 50 boys, who it said died at the school as a result of illnesses or accidents, were buried, blaming poorly kept school records. FDLE closed the case due to the lack of evidence that anyone had died as a result of criminal conduct, and no charges were filed. Investigators say the records do not explain why the boys were buried on school property in the first place. The boys who attended the school were considered "young offenders" of state law and were placed in the school in order to be "separated from older more vicious associates," according to the 2009 report citing the Florida Children's Commission of 1953. Florida's Department of Juvenile Justice closed the school in 2011, blaming budget cuts. Glen Varnadoe is quite happy that the school is closed. He said he's spent a considerable amount of his own money trying to have the remains of his uncle returned to him and his family. "I don't know why you'd want to try to prevent anyone from returning a loved one after having been buried the way they have been buried," he said. "You tell me what their motive is."

[EX Q]: (CNN) -- South African police are investigating abuse allegations at the Oprah Winfrey Leadership Academy, the talk-show host's $40 million school for disadvantaged girls near Johannesburg. Oprah Winfrey, who founded the school this year, has apologized in connection with the incident. Investigators declined to provide details of the alleged abuse and said no charges have been filed. The academy's CEO, John Samuel, said in a statement earlier this month that an internal inquiry was launched based on a claim of misconduct involving a dormitory parent. According to an article in The Cape Argus, a Cape Town newspaper, the dorm parent allegedly grabbed a pupil by the throat and threw her against a wall, the girl claimed. Girls at the school also claimed that the matron swore and screamed at the girls and assaulted them, the newspaper reported Saturday. The newspaper said one of the pupils ran away from the school, blaming the alleged abuse. In an emergency meeting with pupils and parents at the school, Winfrey apologized in connection with the incident. "I've disappointed you. I'm sorry. I'm so sorry," she said tearfully, according to numerous South African media reports. Winfrey's representatives said she flew to South Africa twice in October to meet with parents of girls at the academy, although they would not specify what the meetings were about. Previously, Winfrey -- who has spoken publicly about the abuse she suffered as a child -- issued a statement on October 17 saying, "Nothing is more serious or devastating to me than an allegation of misconduct by an adult against any girl at the academy." In the statement, Samuel said South African child protection services were notified and that the dorm parent was removed from the campus. "We have engaged professional investigators of the highest standing from South Africa and the United States to conduct a fair and impartial inquiry into these claims," the statement said. The school's head has agreed to take a paid leave of absence pending the results of the investigation, although she is not the subject of the allegation, Samuel said. The national prosecuting authority is deciding whether or not criminal charges will be filed. In an October 23 statement, Samuel referred inquiries to the South African Child Protection Services Unit. The academy opened in January with a student body made up of some of South Africa's poorest children. The academy provides its 450 students with textbooks, uniforms and meals. E-mail to a friend .
