The National Commission for Human Rights (Komnas HAM) announced on Thursday that as many as 70 members of a Shiite community in Sampang, East Java are still missing since an attack on Sunday that left two dead and several people badly injured. Another organization said that dozens of people are hiding in the jungle near Sampang.

"Some 24 families have disappeared. If each family consists of three persons, then at least 70 people are missing," Komnas HAM commissioner Hesti Armiwuland said in Jakarta on Thursday, as quoted by Indonesian news portal tempo.co.

Hesti also criticized what she called the government's slow response to the problem, adding it remained unclear how they planned to deal with the situation.

She added that some 340 Shiites seeking refuge at Sampang's Wijaya Kusuma Stadium were living in squalid conditions, with poor sanitation and food. "They are packed like sardines, without a divider between the men and the women," Hesti said. "I've also received reports of spoiled rice."

A mob of some 500 Sunni Muslims attacked Nangkernang village inhabited by a Shiite community in the subdistrict of Omben in Sampang on Sunday. Two Shiites were killed, while dozens of others were injured, including seven that are still in critical condition, according to the latest reports. The attackers also set dozens of houses on fire.

Commission for Missing Persons and Victims of Violence (Kontras) Coordinator Fatkhul Khoir also said on Thursday that some of the Shiite followers had fled to jungle near Sampang after the attack, putting the number near 50.
