Two bomb attacks rocked the Algerian capital yesterday - one on the UN refugee agency — killing at least 62 people with foreigners among the casualties, hospital sources and officials said.

One bomb tore apart tire front of the UN High Commissioner for Refugees (UNHCR) building. A second blew apart a bus packed with university students outside the Supreme Court.

Ten UN staff, all Algerians, were among the dead from an attack on a UN refugee agency building in Algiers on Tuesday, a senior UN official said.

All were in the offices of the UN High Commissioner for Refugees and neighbouring UN Development Programme (UNDP) when the bomb went off, said the official, speaking on condition of anonymity. Several injured were still trapped in the debris several hours after the attack, according to journalists at the scene.

Algeria has been hit by a number of bomb attacks this year -- in which scores of people have been killed — and most have been claimed by al-Qaeda.

Interior Minister Yazid Zcrhouni said a suicide bomber triggered the explosion outside the Algiers office of the UNI ICR.

The front of the red brick building was badly damaged and the UNHCR said staff were among the casualties.

In the second'near-simultaneous attack, a car bomb was detonated outside the Supreme Court as a bus packed with university students passed by, headingfora nearby law faculty. •

Security sources said the bus look the full force of the blast and most of die dead and injured there were students.

" The death toll is very high," the minister told reporters without givinga figure.

Hospital sources said 62 people were killed in the two attacks but did not give a breakdown. They added that several foreigners were among the seriously injured.

The UNHCR office is in the Hydra residential district where the finance and energy ministries and several diplomatic residences are also located.

There were "victims in the offices,” Jennifer Pagonis, a UNHCR spokeswoman at the agency headquarters in Geneva, told AFP. She said no figures were available.

Hydra is normally under tight police surveillance because of die numberofforeigners who live there.

Ambulances with sirens wailing rushed to the two sites where columns of black smoke rose from wreckage.

Security forces threw up road blocks around the city and the interior minister spoke to reporters after visiting the scene.

There was no immediate claim of responsibility for the blasts.

al-Qaeda's offshoot In north Africa said it carried out a series of bomb attacks in Algiers and other pans of the country this year which have left more than 100 dead.

There has however been a relative calm in Islamist-inspired violence since September. Ine four dead recorded in an AFP toll for November was the lowest monthly figure since zMgeria’s Islamist strife erupted in 1992.

More than 100,000 people died in Algeria during a civil war in the 1990s.

On September 6, a suicide attack targeting President Abdelaziz Bouteflika's convoy in the eastern town of Batna killed 22 people and wounded more than 100 others.

l\vo days later, another suicide attack against a coastguard barracks at Dellys, east of Algiers, left 30 people dead and 40 wounded.

A suicide bomber rammed a booby-trapped car into a convoy east of Algiers on September 21, wounding two French engineers and an Italian, in an attack only hours after al-Qaeda called for an offensive against French targets.

In July, 10 soldiers were killed and 35 people wounded when a suicide bomber rammed a truck full of explosives into barracks in Lakhdaria, an Lslamiststronghold.
