Six Filipinos are confirmed dead and four are missing, the nation's foreign affairs ministry said. In addition, 16 Filipinos are alive and accounted for, according to a ministry spokesman.
One Romanian lost his life while four others were freed, the country's foreign ministry said.
Three British citizens were killed, the Foreign Office said Sunday. Three other British nationals and a UK resident are also "believed dead," according to British officials. The Foreign Office confirmed the name of one slain hostage, Garry Barlow, in a statement Monday.
"Garry was a loving, devoted family man, he loved life and lived it to the full. He was very much loved by myself, his sons, mother and sister and the rest of his family and friends and will be greatly missed," the Foreign Office quoted his wife, Lorraine, as saying.
Twenty-two other Britons who were taken hostage have safely returned home.
U.S. State Department spokesman Victoria Nuland on Monday said three Americans had been killed and identified them as Victor Lynn Lovelady, Gordon Lee Rowan and Frederick Buttaccio, who had been previously identified.
Seven U.S. citizens survived the crisis, added Nuland, who declined to comment further citing privacy considerations.
Erin Lovelady described her father Victor, of Nederland, Texas, as a laid-back, understanding and loving man.
"I want people to understand how wonderful my dad was, and how great a dad he was, and how much he's going to be missed by me and my mother and my brother," Erin Lovelady told CNN affiliate KFDM, describing herself as "daddy's little girl."
Gwen Eckholm called Rowan -- her former neighbor in Mesa, Arizona, who recently moved to eastern Oregon -- a "very intelligent, super-nice guy" who told her he felt safe working in Algeria.
He said "we're in a compound in the middle of nowhere, and we've got security, and I'll be fine," Eckholm told CNN affiliate KNXV. "I guess you can't really be secure any place."
