A cliff located in a beach resort in Yogyakarta, Java Island reportedly collapsed on Wednesday during a gathering and rescue teams along with police and the Indonesian Armed Forces have begun their search for victims.
Eleven people are currently missing, and at least four dead, according to local police chief. All those killed were reported to be men.
The cliff slided, sweeping nearby visitors under it as they gathered for the traditional Padusan cleansing ritual before Ramadan, according to the report.
According to eyewitnesses, there were at least 10 people in the immediate vicinity of the cliff-slide.
Officials say that at least four others could be buried under the debris of the 15-metre-high remains of the cliff.
One person who survived the incident is seriously injured, according to rescue officials.
Only two survivors of the incident were found thus far.
