President Barack Obama has condemned deadly New Year’s Eve attacks in Egypt and Nigeria.

In a statement, Obama says the perpetrators of an attack on an Egyptian church have no respect for human life or dignity. He says those responsible for the bomb that killed at least 21 people must be brought to justice for "this barbaric and heinous act." The bombing enraged Christians in Egypt who often complain of discrimination at the hands of Egypt’s Muslim majority.

Obama also says a separate attack near an army barracks in Abuja, Nigeria demonstrates the "bankrupt vision" of those who carry out the attacks. At least four people were killed and 21 wounded while celebrating the new year.

Obama says the U.S. will offer any necessary assistance to Egypt and Nigeria.
