(CNN) -- A rebel group in the Democratic Republic of Congo killed at least 321 civilians and abducted 250 others -- including at least 80 children -- in a previously unreported rampage late last year, Human Rights Watch said in a report released Saturday. The Lord's Resistance Army (LRA) carried out the brutal campaign in northeastern Congo over four days in December, the report said. LRA forces attacked at least 10 villages from December 14 to 17, killing and abducting hundreds of civilians -- including women and children, according to Human Rights Watch. LRA combatants tied up villagers in the nation's remote Makombo area and hacked them to death with machetes or crushed their skulls with axes and heavy wooden sticks, the report said. Most of those killed were adult men, but at least 13 women and 23 children were among the dead -- including a 3-year-old girl who was burned to death, according to Human Rights Watch. The LRA also killed those they abducted who walked too slowly or tried to escape, Human Rights Watch said. According to those who managed to escape, children captured by the LRA were forced to kill other children who had disobeyed the LRA's rules, the report said. In numerous cases, children were ordered to surround the victim in a circle and take turns beating the child on the head with a large wooden stick until the child died, the report said. "The Makombo massacre is one of the worst ever committed by the LRA in its bloody 23-year history, yet it has gone unreported for months," said Anneke Van Woudenberg, a senior Africa researcher at Human Rights Watch. "The four-day rampage demonstrates that the LRA remains a serious threat to civilians and is not a spent force, as the Ugandan and Congolese governments claim." CNN could not independently confirm the massacre. Human Rights Watch said that the roughly 1,000 United Nations peacekeeping troops in LRA-affected parts of northeastern Congo are insufficient to protect civilians. The peacekeeping force is considering removing some troops from the area under pressure from the Congolese government, a move Human Rights Watch warned against on Saturday. The U.N. Security Council is planning to visit Congo in mid-April to discuss the peacekeeping force's plans for withdrawal and the protection of civilians, Human Rights Watch said. The Congolese government denies that the LRA is still a serious threat in the country, which may have contributed to the absence of reports about the December massacre, Human Rights Watch said. "We have been forgotten," an 80-year-old Congolese man whose son was killed during the massacre told Human Rights Watch. "It's as if we don't exist." "The government says the LRA are no longer a problem, but I know that's not true," he said. "I beg of you, please talk to others about what has happened to us." The LRA is led by self-declared mystic and prophet Joseph Kony, who claims his insurgency -- which began in 1986 -- is aimed at replacing Uganda's government, led by President Yoweri Museveni, with a democracy based on the Bible's Ten Commandments. After being pushed out of Uganda in 2005, the LRA now operates in the remote border area between southern Sudan, Congo, and Central African Republic. In 2005, the International Criminal Court issued arrest warrants for senior LRA leaders for crimes they committed in northern Uganda, but those indicted remain at large. The two commanders who perpetrated the December massacre report to one of those indicted leaders, according to Human Rights Watch. The Makombo massacre is the deadliest documented attack by the LRA since killing sprees around Christmas 2008 left scores of Congolese dead, but dozens of other attacks against civilians have been carried out in other areas in recent months, Human Rights Watch said.

It was a shocking and gruesome discovery: three dead infants found in a Massachusetts home so squalid that police officers had to search it in hazmat suits. Now, days later, as investigators continue to search through what the Worcester County District Attorney's Office describes as the home's "deplorable conditions (such as) massive insect infestation, mounds of used diapers and feces," a picture is beginning to emerge of the family that lived inside. And it's a picture so deranged, so unfathomable to a reasonable mind, that even a lawyer for the accused calls the situation "completely inexplicable." Erika Murray was arraigned September 12 on a bevy of charges stemming from the discovery of the dead infants at her home the day before, but she has not been charged in their deaths. The 31-year-old pleaded not guilty to charges of concealing an out of wedlock fetal death, two counts of permitting substantial injury to a child, intimidation of a witness, cruelty to an animal and violating an abuse prevention order, according to Tim Connolly, a district attorney spokesman. Whether or not Murray is the mother is not known by authorities for certain at this point, but her attorney assumes that she is. "My expectation is that it will be confirmed that they were indeed hers," Keith Halpern told CNN. Murray lived in the now-condemned single family home with her longtime boyfriend, Ray Rivera, and the couple's children. Just how many children lived with them in the vermin-infested 1,150-square-foot home, however, depends on which parent you ask: of the four living children that the state removed from the home on August 28, Murray told investigators that Rivera, 38, only knew about two of them. The other two -- a 3 year old and an infant, according to Halpern -- were apparently not only born in secret but lived hidden from their father amid mountains of garbage under the same roof. Rivera also "presumably" did not know about the ones that had died, at least according to the account Murray has told authorities, Halpern said. "It is a mystery to me how Mr. Rivera could have failed to notice (the) numerous pregnancies (of) the woman with whom he shared a bed," said Halpern. "It's a mystery to me how he could have failed to realize that there were two children living under the same roof as him, and he didn't know about it." CNN was unable to reach Rivera or members of his family Sunday evening. He has not been charged with any crime, and there is no public record of physical abuse. 'Prisoner of her own fear' Halpern said that while his client's explanation "is not based in reality," the situation  Murray came to be in was the result of fear, not malice. "She was terrified of the pregnancies being discovered," said Halpern. "She was terrified of the two younger children being discovered. Why? I don't know the answer to that." Whether based in reality or not, Halpern said Murray was "a prisoner of her own fear" and suggested it was that fear that explains the three infants found dead in her home. "Try to imagine the state of mind of a woman who attempts to hide a pregnancy,  go into labor and deliver children -- at least twice, but presumably five times -- on her own." "I feel certain that she did not do anything to harm any of these children," he said. "I don't think there will be a determination that they were killed." Though Halpern said he has yet to consult with a pathologist, he said it is not clear if they were ever alive to begin with or if they were all stillborn. Abuse suspected in 2007 . The state's removal of the four living children at the home last month was the result of the filing of what's called a 51A report in Massachusetts, according to Alec Loftus, a spokesman for the state's office of Health and Human Services. A 51A can be filed by any citizen with reason to believe that a child has been abused or neglected. This was not the first time a 51A had been filed when it came to that home, according to a Massachusetts Department of Children and Families spokeswoman. Cayenne Isaksen said such a report was previously received in 2007, but that "it was unsupported and therefore no case was opened." For now, Isaksen said DCF has Murray's four children in its care and is focused on  "ensuring (their) safety and well-being and providing them with the proper medical care, support and services they need," she said. Connolly said that the family caring for them has no public statement to make at this time. Murray's case was adjourned to October 14. Investigators, meanwhile, remain at the scene digging through the squalor. "Our investigation will continue for quite some time," said Joseph Early, the Worcester County District Attorney.
