Israel's prime minister says there has been a significant drop in the rate of Palestinian attacks against Israelis.

Benjamin Netanyahu said Sunday he was citing the figures of Israel's Shin Bet security service carefully because "this trend could be reversed." But there have been no casualties over the past two and half weeks, the slowest stretch in a seven-month wave of stabbings, shootings and vehicular attacks that has killed 28 Israelis and two Americans.

During this time, about 187 Palestinians have died by Israeli fire. Israel says most of them were attackers, and the rest died in clashes with Israeli security forces.

Israel blames the attacks on incitement by Palestinian leaders and social media. Palestinians say the violence stems from frustration at nearly five decades of military occupation.
