Cianjur – Around 150 militant Muslims have swept through housing complexes where members of the Ahmadiyah sect live, sealing off and vandalizing four mosques belonging to the sect.

Using motorcycles to roam around areas in the West Java regency on Wednesday, the unknown group had ended their expedition by the afternoon without any intervention by police, detik.com news portal reported.

They sealed off Ahmadiyah mosques in Penyairan, Cisakra, Ciparay and Neglasari, all in Cianjur, before spraying paint over the walls of the mosques.

There was no violence reported as Ahmadiyah members kept themselves hidden. "We were all very afraid so we did not come out of our houses. We just did not want anything to happen to us," Dili Sadili, an Ahmadiyah leader in Penyairan, said.

The situation remained tense even after the group had left the housing areas, local residents said.
