The most common tactic used by Palestinians during the Intifada was throwing stones, molotov cocktails, and burning tires. The local leadership in some West Bank towns commenced non-violent protests against Israeli occupation by engaging in tax resistance and other boycotts. Israel responded by confiscating large sums of money in house-to-house raids. As the Intifada came to a close, new armed Palestinian groups—in particular Hamas and the Palestinian Islamic Jihad (PIJ)—began targeting Israeli civilians with the new tactic of suicide bombings, and internal fighting amongst the Palestinians increased dramatically.
