WORO, Nigeria — Weeks after residents of two Nigerian villages ignored a letter from militants announcing they would come to spread their extreme form of Islam, gunmen arrived on motorbikes and embarked on a 10-hour frenzy of killing.
The attackers went from door to door, shooting and setting homes and shops ablaze in the mostly Muslim villages of Woro and Nuku. Later, residents told The Associated Press, they went into a mosque, announced the call to prayer and shot everyone who turned up.
In the deadliest attack in Nigeria in several months, the extremists rounded up villagers, tied their arms behind their backs, lined them up and shot them in the head. Authorities say they slaughtered at least 162 people, while villagers say the toll is higher and that the men kidnapped many others.
The attack is the latest in a surge in violence in the state of Kwara, as well as other conflict hot spots, as armed groups in Nigeria challenge the state's authority and compete with one another.
The attack came out of the blue
Immediately before the attack, life had been quite normal in the quiet neighboring villages, where most residents are farmers, roughly 500 kilometers (300 miles) from the state capital.
Umar Bio Kabir, a 26-year-old schoolteacher, was playing football with his friends when they saw the attackers. They ran for their lives, but not everyone who was playing made it.
''God said I would survive or else I would have been among the dead,'' he said.
