Islamists probed amid new violence

Investigators probed an Islamist sect yesterday over the suicide bombing of the UN headquarters in Nigeria that killed at least 21 people in one of the bloodiest attacks targeting the world body.
Fresh violence hit Sunday when gunmen stormed the home of a local government chairman in the northeast and shot him dead. An attacker also threw a bomb onto the property of an ex-government minister, but there were no injuries.
The UN's deputy chief held talks with Nigerian President Goodluck Jonathan on Sunday and afterward said the "perpetrators must be brought to justice," while vowing that the attack would not deter the work of the United Nations.
Deputy UN Secretary General Asha-Rose Migiro was due to leave Nigeria yesterday, but United Nations security chief Gregory Starr would remain in the country for now as the probe continues, said UN spokesman Martin Dawes.
Police said an all-encompassing investigation was being carried out that would look at the Islamist sect known as Boko Haram, which has claimed responsibility, as well as a range of other factors and past attacks.
"It's a multi-dimensional investigation so that a complete stop can be put to these incidences," said police spokesman Yemi Ajayi. "Boko Haram is still part of what we are looking at."
No arrests had been made. He declined to reveal who was involved in the investigation, but the US embassy has confirmed that FBI agents were in Nigeria.
The sect has claimed responsibility for the attack, but analysts have cautioned that while at least one faction of the Islamist group may be involved, it was too early to draw firm conclusions.
Friday's attack saw the bomber make his way through two gates at the heavily guarded compound before slamming his car into the entrance of the building. In addition to the 21 killed, 73 have been confirmed injured.
