- As 18 detained for China apartment fire that claimed 19 lives
At least 50 people have been killed in a suicide bombing in the eastern Nigerian state of Adamawa, police say.
A bomber struck inside a mosque packed with worshippers during morning prayers in the town of Mubi.
Witness Abubakar Sule told AFP news agency that it appeared the bomber was part of the congregation.
No-one has said they were behind the bombing but the Islamist militants Boko Haram typically target crowded places in northern Nigeria.
Some 20,000 people have been killed in Boko Haram’s eight-year insurgency.
The BBC’s Ishaq Khalid reports that Boko Haram militants have recently stepped up suicide bombings in Nigeria’s north-east after the military recaptured territories previously controlled by the group.
At least 45 people were killed in a suicide bomb attack in the same state last December.
In that attack two female suicide bombers detonated their explosives in a busy market.
In the meantime, Chinese police have detained 18 people in connection with a fire in an apartment that claimed 19 lives.
The fire broke out Saturday night at the three-story apartment at Xinjian Village of Daxing District at the southern suburb of the city.
Among the victims, eight were under 18 years old, He Rui, deputy chief of Daxing District, said at a press briefing late last night.
Eight persons were taken to a hospital. Seven of them are out of danger and one remains in a critical condition, state-run Xinhua news agency quoted Rui as saying.
A preliminary investigation showed there was a 5,000- square-meter refrigeration facility under construction in the basement of the apartment. Fire-fighters suspect the fire might have started there.
The 18 detainees include seven who managed the apartment block, seven electricity workers, and four construction workers at the refrigeration facility. None of the 11 workers holds qualifications as required by the authority, police said.
More than 400 people lived in the apartment block and all have been relocated, He said.
The district government has set up medical, legal and family teams to deal with affairs arising from the deadly fire. They contacted 95 family members of the victims.
Police are investigating other suspects.
Beijing has ordered a 40-day city-wide safety check. Local officials are urged to check every village and every courtyard for safety risk.
