This comes after billboards bearing the image of Anwar Ibrahim with the 'Malaysia Madani' message were vandalised.

The attack comes after weeks of violent clashes between members of the Kuki ethnic group, who mostly live in the hills, and Meiteis, the dominant community in the low lands of the state.

The Mont Valerien monument in Suresnes has been vandalised with the words 'Anti Pass', with the style of the double-s reminiscent of that used by Nazis for their SS inscriptions, authorities say.

The words 'jangan buka bunyi terlalu kuat' had been painted on the wall near the main entrance, according to the muezzin.
