ROME (AP) – Police in Milan and London on Thursday arrested four Tunisians who allegedly provided logistical and financial support to an al-Qaida affiliate and who were linked to the April bombings in Algiers that killed 30, Italian officials said.

Three men were picked up on terrorism charges in Milan and one was arrested at his home in north London, according to police in both cities.

The group allegedly recruited extremists that were sent to terrorist training camps in Afghanistan before joining militants in Algeria, Tunisia, Chechnya, Bosnia or Afghanistan itself, Italian police said in a statement.

The cell, allegedly part of the Salafist Group for Call and Combat – or GSPC – also planned attacks in Italy, said police Colonel Domenico Grimaldi, who led the investigation.

“There were also plans for Italy, but fortunately they were not carried out,” he told SKY TG24 TV. “However, we know that other members of the group were killed in Algeria and Tunisia.”

Colonel Grimaldi did not elaborate. The police said the Milan-based cell was connected to the April 11 Algiers bombings as well as a deadly shootout between police and gunmen tied to the GSPC in January in Tunisia.

Algeria’s GSPC, which changed its name to Al Qaeda in Islamic North Africa when it announced its alliance with Al Qaeda in January, is on the U.S. list of terrorist organizations. The group claimed responsibility for the twin suicide bombings in Algiers.

In its recruiting activities, the Milan cell provided false documents, as well as apartments, cars and communication devices registered under false names, the Italians said in the statement. Police also tracked a flow of money of tens of thousand of dollars destined for Afghanistan through Europe, North Africa and the Middle East.
