Nigeria's military says it has rescued 234 more girls and women from a Boko Haram forest stronghold in the country's north-east.
The announcement by the Nigerian Defence Headquarters brings the number declared rescued this week to more than 677.
There have been reports that some women fought the troops, with Boko Haram using them as an armed human shield.
It is not known how many girls, women, boys and men Boko Haram has kidnapped over its six-year-old rebellion.
The 200 girls rescued in an army operation in Nigeria are not those kidnapped in Chibok last year, an army spokesman has said.
Earlier, the Nigerian Army said it has rescued 200 girls and 93 women during a military operation in the Sambisa Forest after destroying three Boko Haram camps.
But a spokesman for the army has confirmed that the girls were not those kidnapped from schools in Chibok by Islamist militant group Boko Haram in April 2014.

Boko Haram will soon know the strength of our collective will. We should spare no effort.
In tackling the insurgency, we have a tough and urgent job to do.
Nigerian election winner Muhammadu Buhari says his country proved it has "embraced democracy" after his historic victory.
Buhari, 72, became the first politician to unseat a sitting leader at the ballot box yesterday.
"We have proven to the world that we are people who have embraced democracy - we have put one-party state behind us," he said.
Mr Buhari also paid tribute to outgoing president Goodluck Jonathan for relinquishing power, telling journalists: "President Jonathan was a worthy opponent and I extend the hand of fellowship to him."

The new First Lady of Nigeria has hailed a "triumphant show of democracy" after her husband and opposition leader Muhammadu Buhari won the country's election.
All Progressives Congress leader Buhari, who said he had been "converted" to democracy after first seizing power three decades ago in a military coup, is the first Nigerian to oust a sitting president through the ballot box.
His wife, Aisha Buhari, took to Twitter to share her joy as the results rolled in, saying she was "so proud" of her husband and his team.
I am excited for the future of this nation as We now have a mandate for Change.
We must see this as a triumphant show of democracy, a change for the better.
Nigerians are aware now more than ever that the people have the power to sway the fate of a nation.
