Jakarta – Four hunger strikers from several Jakarta universities collapsed Sunday, six days into their strike.

They had their lips sewn up in a show of support for people claiming to be the victims of the construction of extra-high voltage electricity wires in their neighborhoods.

Donnie and Rifsia Iga, both from TAMA University in Jagakarsa, South Jakarta, and Simon and Sadrak, from Indonesian Christian University in East Jakarta and Satya Negara University in South Jakarta respectively, were admitted to Yadika Hospital.

The student protest was held on the Jl. Pondok Indah campus of Satya Negara University.

"They are in a very weak condition after going without food for six days," said Roni, the spokesman for the group of 20 hunger strikers.

The head of Yadika's emergency room, Hendrik Sulo, said all of the students – who refused to have their stitches removed – would need three days to recover.
