Jawaher Abu Rahmah, a 36-year-old kindergarten teacher, was killed over the weekend after she choked on tear gas while watching the weekly demonstration at her village. Residents and human rights activists from at home and abroad demonstrate against the separation fence that was built on village land. Abu Rahmah died less than two years after her brother Bassem was killed by a tear-gas canister fired directly at his chest at a similar protest. A third brother, Ashraf, was caught on camera as he was shot by Israeli soldiers while he was handcuffed.

The demonstrations at Bil'in, which have been going on since work to build the fence on village land began in February 2005, are entirely legitimate. The residents have the right to protest the theft of their land for the giant settlements set up around their village. More than three years ago, following such demonstrations, the Supreme Court ordered that the fence's route be moved to give the village back some of its land - about 700 dunams. The defense establishment has yet to carry out this ruling.

Since the demonstrations against the fence began in the West Bank, 21 protesters have been killed, according to Palestinian sources. This is a chilling statistic that should greatly trouble every Israeli. So should the death of Abu Rahmah. According to the demonstrators, the Israel Defense Forces used particularly large quantities of gas on Friday. An Israeli doctor who takes part in the protests, Daniel Argo, told Haaretz that some tear gas is less dangerous than the kind used by the IDF. So it's not clear why the army chooses to use the more dangerous type.

The IDF should allow the demonstrations at Bil'in to take place. It should act only when there is danger to life and property. And even then it should act as security forces do in democratic countries when there are demonstrations. Just as the settlers' protests against the Gaza disengagement passed without deaths, so should the Palestinian protests against the fence pass. There are enough ways to break up demonstrations, if this is at all necessary, without risking the lives of the participants.

Abu Rahmah died in vain. She didn't endanger anyone. There's no need to mention the countries where the regimes kill people who demonstrate against them. Israel must not become one of them.
