Here's the basics from Wiki. Dig around if you want more gruesome details from other sources.
https://en.wikipedia.org/wiki/Algerian_Civil_War#Village_massacresAt this point, however, a new and vital problem emerged. Starting around April (the Thalit massacre), Algeria was wracked by massacres of intense brutality and unprecedented size; previous massacres had occurred in the conflict, but always on a substantially smaller scale. Typically targeting entire villages or neighborhoods and disregarding the age and sex of victims, killing tens, and sometimes hundreds, of civilians at a time.
These massacres continued through the end of 1998, changing the nature of the political situation considerably. The areas south and east of Algiers, which had voted strongly for FIS in 1991, were hit particularly hard; the Rais and Bentalha massacres in particular shocked worldwide observers. Pregnant women were sliced open, children were hacked to pieces or dashed against walls, men's limbs were hacked off one by one, and, as the attackers retreated, they would kidnap young women to keep as sex slaves. Although this quotation by Nesroullah Yous, a survivor of Bentalha, may be an exaggeration, it expresses the apparent mood of the attackers:
"We have the whole night to rape your women and children, drink your blood. Even if you escape today, we'll come back tomorrow to finish you off! We're here to send you to your God!"
https://en.wikipedia.org/wiki/Rais_massacreThe hooded attackers arrived about 1 am in trucks and cars, armed with shotguns, knives, axes, and bombs. They continued killing the village's men, women, children, and even animals until dawn (about 6 am), cutting throats and taking the time to burn corpses; young women, however, were abducted instead of being killed. In some cases, they left severed heads on doorsteps. They mutilated and stole from the dead, and committed atrocities against pregnant women. They burned and bombed some houses. The villagers tried to flee or hide. Army units stayed outside the village, shooting at fleeing villagers, but not attempting to enter the village until after the attackers, carrying away some 20 young women, left at dawn.
https://en.wikipedia.org/wiki/Bentalha_massacreOn September 22, at 11:30 pm, explosions rocked the Hai el-Djilali neighborhood on the southwest side of Bentalha, and attackers began pouring in from the orange groves to the neighborhood's southeast. They began methodically going from house to house and slaughtering every man, woman, and child they found within. Screams and alarms filled the air as a helicopter circled overhead. The attackers were armed with machine guns, hunting rifles, and machetes; some, according to Nesroullah Yous (see below), were dressed in dark combats, some in the Islamists' trademark kachabia, with balaclavas and beards. They recognized some of the locals, calling them by name. They proceeded, dashing babies into walls[citation needed], cutting off limbs, cutting throats, raping and then killing women.
Allahu akbar.
Initially I was surprised you hadn't heard of this, since it was "only" 17 years ago, but I suppose you were in nappies then.
