Toll in terror attack on UN building in Nigeria rises to 23

Starr told reporters that no advance warning was received before the attack.

Migiro laid wreaths at the UN compound and made her way past broken glass and twisted metal during a tour of the badly damaged five-storey building.

“It is a shocking incident,” she said. “This attack is against global peace. It is also against humanity because those who work here come from different countries.”

She later visited victims at the national hospital and held talks with President Goodluck Jonathan.

Jonathan,who had toured the UN premises had said that all Nigerians are shocked by the attack.

“Terrorist attacks on any individual or part of the world is a terrorist attack on the rest of the world,” he added.

“Terrorists don’t care about who is anywhere.”

“We will work with the UN and other world leaders to ensure that terrorism is brought under control.”

The radical Islamist group,Boko Haram has said that it was behind the blast.
