There has been strong and almost universal condemnation of last night's suicide bomb attacks in Casablanca.

Forty-one people were killed and around 100 injured when suicide bombers struck in Morocco's biggest city.

Moroccan police say they have arrested 27 Islamists in connection with attacks.

A government source said the 27 were arrested in a series of police raids.

The Moroccan Interior minister said the attacks were carried out by a group of 14 people divided into five teams.

Five bombs were set off almost simultaneously by suicide bombers at a time when the city centre was crowded with people enjoying a night out.

Officials belive that as many as 10 of the dead might have been assailants.

A Jewish community centre and a Spanish club were among the targets of the second major attack within a week on an Arab kingdom with historically close ties to the United States. Saudi Arabia was hit by multiple suicide bombings on Monday.

Three French nationals, two Spaniards and an Italian were reported to be among those killed.

No group has claimed responsibility for the bombings, but the apparently coordinated nature threw suspicion on Osama bin Laden's al Qaeda network.

Some attackers made direct raids, but other blasts were triggered by car bombs.

Among the targets were a luxury hotel, a Jewish club and a Spanish restaurant. Two policemen were killed outside Belgium's consulate, which bore the brunt of a blast apparently aimed at a Jewish-owned Italian restaurant opposite, embassy staff in the Moroccan capital Rabat said.

US President, George W Bush warned on Friday of 'killers on the loose' as terror alerts spread around the world after Monday's attacks in the Saudi Arabia that killed 34 people, including eight Americans.

President Bush, in his weekly radio address, said the enemies of freedom were not idle but neither was the United States.

He said the US-led war on terror had weakened al Qaeda, but the United States was hunting from Pakistan to the Philippines to the Horn of Africa for any suspects.

Many countries speculated that Morocco was targetted to warn Rabat against pursuing its moves towards democracy. Morocco said that it would not be swayed from its democratic path.

'Morocco will continue its democratic and modernisation project and will firmly deal with all those who want to drag the country into the twists and turns of destabilisation,' Communications Minister Nabil Benabdellah said.

The Russian foreign ministry said the blasts were the work of an international network that was probably behind the recent bombings in Riyad and Chechnya.

Here, Minister for Foreign Affairs, Brian Cowen, condemed the bombings and expressed his sympathy with the victims and their relatives. He said the killing of innocent life was abhorrent and contrary to all civilised vaues. It has no justification, said Mr Cowen.
