The New York Times: Less than a week after Muhammadu Buhari, a former army general, took over as Nigeria’s president and vowed to crush Boko Haram, the group has intensified its attacks in the country’s northeast, killing scores in a series of assaults and suicide bombings.

Twenty to 50 people were killed in the latest attack on Tuesday. A man disguised as a salesman blew himself up in a slaughterhouse in Maiduguri, the capital of Borno State and the biggest city in the region, officials said.

Early on Tuesday morning, residents at the city’s southern edge also awoke to the sound of exploding rocket-propelled grenades and automatic gunfire from the militants, and a similar attack took place late Saturday night near the airport, killing at least eight people.
