CASABLANCA, Morocco, May 18 (IslamOnline.net & News Agencies) - Morocco's King Mohammed VI Sunday, May 18, toured the devastation caused by the wave of bombings that left 41 dead in Casablanca, as a Moroccan official said the Kingdom was about to "shed light" on the attacks.

Under heavy security, the king stopped first at the Farah hotel, whose entrance was blown apart Friday, killing a security guard and porter who had tried to stop three bombers from getting inside.

The Farah is among the largest of Casablanca's international hotels, and was one of the five sites hit in the bombings, in which at least 28 people were killed along with 13 assailants.

The king also visited the Casa de Espana, a private Spanish club where at least 18 people were killed, and a Jewish cultural center also in the heart of Morocco's largest city and economic capital.

UN Secretary General Kofi Annan called Sunday for an international campaign to stamp out “terrorism” after bomb attacks claimed scores of lives just days apart in Morocco and in the Saudi capital Riyadh, where 34 people were killed last Monday, reported Agence France-Presse (AFP).

Following the Casablanca attacks, in which six foreigners were killed - three French nationals, two Spaniards and an Italian - police announced more than 30 arrests, including that of one would-be bomber who survived.

Communication Minister Mohammed Benabdallah told AFP Sunday that Morocco would be able soon to "shed light" on the attacks, and that the investigation was progressing very rapidly.

He said investigators had established that the 14 bombers, all thought to be Moroccan, belonged to "an international network," without elaborating. Six of the dead bombers have been identified, officials said Saturday.

Justice Minister Mohamed Bouzoubaa said investigators had linked the assailants to a banned Islamic Moroccan group, Assirat al Moustaqim (The Straight Path), and that some had arrived in Morocco "recently from a foreign state," without naming the country.

Several Assirat al Moustaqim members were sentenced in January to up to 20 years in prison for stoning a man to death under an Islamic Fatwa.

Mohammed VI, who pledged medical aid to the scores of people wounded in the attacks, did not speak during his somber tour of the bombing sites.

The Casablanca attacks came amid warnings that al-Qaeda was planning fresh strikes in the wake of the U.S.-led invasion of Iraq.

U.S. officials have identified an Egyptian al-Qaeda leader Saif al-Adel as an organizer of the Riyadh attacks, and the Washington Post reported Sunday that he is thought to have become the network's top military officer after Muhammad Atef was killed in Afghanistan in 2001.

Morocco, a staunch U.S. ally although it opposed the Iraq invasion, was cited among a list of "apostate" Muslim nations - along with Jordan, Nigeria, Pakistan, Saudi Arabia and Yemen - in a cassette message attributed to Bin Laden distributed to the media in February.

The government has come under fire from Islamic groups for delaying municipal elections due to be held in June, a move the local press said was linked to the growing influence of Islamic groups in the country.

In elections last year, the first under Mohammed VI, an Islamic movement tripled its parliamentary presence to become a dominant opposition voice.

The rise of the Party for Justice and Development has been seen as a popular protest at the failure of mainstream parties to address some of the kingdom's deep-rooted problems, which include high unemployment and great disparities in wealth underscored by a proliferation of urban slums.

The party issued a statement condemning the attacks and calling on people to "rally to the sacred values of the country, to unite around King Mohammed VI and to consolidate what has been achieved in the country in the field of freedoms."

Many suspected members of Islamic groups have been arrested in Morocco in recent months, and U.S. officials have praised Rabat's cooperation in exchanging intelligence on “terror suspects” and actively pursuing individuals believed to be associated with al-Qaeda.

However, while the U.S. blames the Casablanca attacks on al-Qaeda network, many ordinary residents of the city place the ultimate blame on U.S. foreign policy.

"Since September 11 (2001), the Americans have been constantly seeking to bully and destabilize the whole world," political science student Mohammed Baadi told AFP.
