Between 2005 and 2010, mosques in the Netherlands were vandalized 117 times, according to Radio Netherlands today which quoted Dutch social researcher, Ineke van der Valk.
The acts of vandalism were motivated by a hatred of Islam, the researcher was quoted saying.
In 43 cases, the mosques were daubed with offensive symbols or slogans. In 37 instances, the mosques sustained material damage.
In 99 of the incidents, the police failed to find any of the culprits.
Most of the vandalised mosques in the Netherlands are located outside the major cities.
There are some 450 mosques in the Netherlands, which has a population of more than 16.5 million. Some five percent of the population is Muslim, some 44 percent Christian and over 41 percent agnostic, said the radio.
