Suspected jihadists massacred at least 160 civilians, including around 20 children, in a village in Burkina Faso's volatile north, the deadliest attack since Islamist violence erupted in the West African country in 2015, local officials said on Sunday (Monday in Manila).

The slaughter, which happened around 2 a.m. on Saturday (9 a.m. in Manila) followed the slaying of 14 people late Friday in the village of Tadaryat in the same region, where jihadists linked to Al-Qaeda and Islamic State have been targeting civilians and soldiers.

In Solhan, in the region near the borders of Mali and Niger, local sources said they have recovered a total of 160 bodies from three mass graves. "It's the local people themselves who have started exhuming the bodies and burying them after transporting them," one local source said.

An earlier toll from local sources had put the dead at 138, while a government toll stood at 132 dead and around 40 wounded as of late Saturday.

In Solhan, a local official said the "situation is still volatile... despite the announcement of military operations," adding that residents were fleeing to the nearby towns of Sebba and Dori. "Many people lost everything after their homes and belongings were torched," he said.

President Roch Marc Christian Kabore on Saturday condemned the massacre in Solhan as "barbaric" and "despicable." "We must remain united and solid against these obscurantist forces," Kabore said.

Declaring three days of national mourning through Monday, the government stated that "terrorists," a term for jihadists, killed civilians of all ages and set fire to homes and the main market.

A security source lamented "the heavy human toll, the worst recorded to date," while warning it could still increase. United Nations Chief António Guterres' spokesman said he was "outraged" over the massacre.

Guterres "strongly condemns the heinous attack and underscores the urgent need for the international community to redouble support to member states in the fight against violent extremism and its unacceptable human toll," Stephane Dujarric said in a statement, offering Burkinabe authorities the United Nations' "full support."

Meanwhile, French Foreign Minister Jean-Yves Le Drian said he would visit the former French colony "this week," saying he would reiterate Paris's "solidarity" after speaking with Kabore by phone.

After Sunday's Angelus prayer at the Vatican, Pope Francis said he also prayed for "the victims of the bloodshed... in a town of Burkina Faso."

"I am close to the family members and to the entire Burkinabe population that is suffering a great deal," Francis added. "Africa needs peace and not violence!"
