London: Special forces who raided a house in Verviers in an anti-terror operation found Kalashnikovs, handguns, ammunition, cash and bomb-making equipment at the spot, as per reports.
At the same time, false documents and police uniforms were also found, as per a report in 'The Independent'.
Reports said that the gun found at the spot were similar to the ones used by the Kouachi brothers, who had attacked the office of French satirical magazine, Charlie Hebdo, in Paris on January 07, killing 12 people, including its editor.
Meanwhile, Belgium was on high alert on Friday, while German and French police made fresh arrests to put Europe on edge a week after the Islamist attacks in Paris.
The series of raids across the continent highlighted fears about young Europeans travelling to fight war with the Islamic State and other extremist groups in the Middle East, and then returning to launch attacks on western targets, as per AFP.
In Belgium, officials said they had averted "imminent" large-scale attacks on police targets after raiding the terror cell in Verviers, near the German border, whose members had recently come back from Syria.
Police shot dead the two suspects in a gun battle after they opened fire on officers with heavy weapons, and arrested a third man, while there were several search operations in Brussels and its suburbs.
Prime Minister Charles Michel raised Belgium's terror alert to its second highest level, security was tightened and Jewish schools in the port city of Antwerp closed today due to fears of further trouble.
The raid and a series of related search operations across Belgium were now "over" but authorities were now seeking to "exploit the information" they had obtained, Foreign Minister Didier Reynders said, as per AFP.
"The threat was to the police forces," he said of the planned attacks.
Europe has been on alert since the attacks on Charlie Hebdo and a Jewish supermarket which 17 people were killed.
