The Guardian reports: Islamist insurgents retreating from Timbuktu set fire to a library containing thousands of priceless historic manuscripts, according to the Saharan town’s mayor, in an incident he described as a “devastating blow” to world heritage.

Hallé Ousmani Cissé told the Guardian that al-Qaida-allied fighters on Saturday torched two buildings that held the manuscripts, some of which dated back to the 13th century. They also burned down the town hall, the governor’s office and an MP’s residence, and shot dead a man who was celebrating the arrival of the French military.

French troops and the Malian army reached the gates of Timbuktu on Saturday and secured the town’s airport. But they appear to have got there too late to rescue the leather-bound manuscripts that were a unique record of sub-Saharan Africa’s rich medieval history. The rebels attacked the airport on Sunday, the mayor said.

“It’s true. They have burned the manuscripts,” Cissé said in a phone interview from Mali’s capital, Bamako. “They also burned down several buildings. There was one guy who was celebrating in the street and they killed him.”

He added: “This is terrible news. The manuscripts were a part not only of Mali’s heritage but the world’s heritage. By destroying them they threaten the world. We have to kill all of the rebels in the north.”

On Monday French army officers said French-led forces had entered Timbuktu and secured the town without a shot being fired. A team of French paratroopers crept into the town by moonlight, advancing from the airport, they said. Residents took to the streets to celebrate.
