Bil'in , West Bank ( CNN ) -- Tear gas , stun grenades , rubber bullets and rocks : It must be Friday afternoon in the West Bank village of Bil'in . It 's billed as a nonviolent protest against what Israel calls its security barrier , what the Palestinians call the apartheid separation wall . The barrier separates the villagers from their farmlands . Protesters come from all over the world to support the Palestinian cause . A few Palestinian youths covering their faces with scarves throw stones at a couple dozen Israeli soldiers in full riot gear and armed with tear gas , stun grenades and bullets . The protest soon degenerates into chaos as it has nearly every week for the past five years . Six protesters have been killed in Bil'in and the neighboring village of Na'alin since July 2008 , according to the Palestinian group , Popular Struggle , one of several organizers of the weekly protests . Several hundred have been injured by tear gas canisters and Israeli bullets . One hundred Israeli soldiers have been injured from stone throwing , according to the Israeli military . The organizers say they have little control over the youths who prefer to throw stones at the rallies . They insist that non-violence is the best weapon they have to fight against Israel 's wall and occupation . Israel has increased its nighttime raids into the West Bank in recent months , arresting those it believes have acted violently or those who are suspected of organizing the protests . `` They can not be above the law , and that 's what we 're dealing with , '' Israel Defense Forces spokesman , Peter Lerner said , referring to the protest organizers . Critics say Israel is simply arresting those who oppose its policies towards the Palestinians . Mohamed Othman , one of the organizers of Stop the Wall campaign , was detained in September upon his return from Norway where he was lobbying the government for support . He said he was held for four months -- three in solitary confinement -- then released without charge . Israel does not comment on these cases . `` We can see that Israel is starting to be afraid of the popular resistance because it 's coming from inside the people and the people decide , '' Othman said . Israel has arrested at least 150 protesters from the two villages ' demonstrations over the past two years , according to Popular Struggle . More than 30 are still locked up , the organization said . The Israeli military told CNN it was checking those figures . One coordinator of the Bil'in Popular Committee Against the Wall , Abdallah Abu Rahmah , also a teacher , was arrested in December . One of the charges against him was arms possession for collecting tear gas canisters used by the Israeli military against demonstrators and showcasing them . The anti-wall demonstrators say this is a grass-roots movement . The Israeli military accuses those it has arrested of incitement . The IDF denies it has changed its tactics in dealing with the anti-wall protesters , even though the number being arrested has risen sharply . The IDF on the ground now considers Bil'in a closed military zone on Fridays . CNN was refused access by Israeli military forces stationed outside the village , who said only those who lived in the neighborhood could enter . But IDF spokesman Peter Lerner said the closure was meant only for protesters . A few hours later , in Bil'in , the Israeli soldiers withdrew from the village under cover of tear gas . Some Palestinian youths followed them with stones , while the vast majority of nonviolent protesters head home . Same time , same place , next Friday .
Also , Israeli ##s protest every Friday night in two West Bank villages . Object of protest is Israel 's security barrier ; Palestinians call it a wall of separation . Palestinian group : Six Palestinians have been killed in two villages since July 2011 . Despite the mayhem , protest is billed by organizers as nonviolent .
