During the weekend of attacks, a police inspector was assassinated Sunday after being stopped with his family in the Nigerian city of Maiduguri. 

The inspector was on his way to a mosque to pray with his family when gunmen stopped their car. The attackers ordered the family away before shooting the inspector. 

This is just the latest in a string of a weekend of attacks. Churches and mosques were bombed and extremists fought police with guns in the streets.

Boko Haram is the sect responsible for the attacks, according to Red Cross officials. The sect, whose name means "western education is sacrilege," is seeking to impose sharia law on the country's 160 million people. The southern region is predominately Christian while the north is heavily Muslim. 

Boko Haram spokesman Abul Qaqa said the Nigerian government was the true aggressor. 

"We will continue attacking federal government formations until security forces stop their excesses on our members and vulnerable civilians," Qaqa told the Nigerian Daily Trust.

The U.S. Embassy issued a warning Saturday of possible attacks on American hotels in Nigeria. 

"We are ready for them, we are going to comb every place in the state until we find and deal with them. Our men are ready," police commissioner Suleiman Lawal told Reuters. 

Nigerian security forces said they were searching for those responsible for the coordinated attacks. 

Eid al-Adha is the "Festival of Sacrifice." Nigeria is Africa's top oil-producing nation. Its economy is growing at 8 percent a year and efforts to shore up its finances have proven unpopular.
