I encourage people to continue to follow advice and guidance shared by policing partners through their official channels over the coming days and weeks.
Dw i am annog pobl i barhau i ddilyn y cyngor a'r arweiniad sy'n cael ei rannu gan bartneriaid o fewn yr heddlu drwy eu sianeli swyddogol dros y dyddiau a'r wythnosau nesaf.
