Dozens killed in Nigeria attacks

The violence underscores the ongoing security challenges facing Africa's most populous nation, with various armed groups operating in the northwest and central regions.

Survivors of the church attack described a harrowing scene as gunmen opened fire on congregants during a holiday worship service.

While the military's rescue operation was successful, many families are still mourning those lost in separate incidents.

The government has vowed to increase security presence in vulnerable areas to prevent further holiday-related violence.
