As of 18 May 2021, the Palestinian militant group Hamas and other militant groups continue to launch rocket and mortar attacks on Israel, while the Israeli Defense Forces (IDF) continue to launch airstrikes against militant targets in Gaza. Thus far, Hamas militants have launched multiple rockets at towns along the Gaza-Israel border and in central Israel following a five-hour pause to allow humanitarian access to the bombarded areas. The Palestinian mortar attacks killed two people in the Israeli city of Eshkol and wounded 10 others; details regarding Palestinian casualties are unknown at this time.

Meanwhile, in the West Bank, Palestinian media reports indicate that clashes occurred between youths and Israeli police at the Shuafat camp checkpoint in Jerusalem and in the city of Jayus. Additionally, Israeli forces disrupted an attempted attack on Israeli soldiers in the city of Hebron. Security personnel shot and killed a Palestinian militant armed with an improvised firearm, a knife and an improvised explosive device (IED). Meanwhile, The High Follow-up Committee for Arab Citizens of Israel began a general strike in coordination with the Fatah movement in the West Bank, which has called for a day of rage against the Israeli occupation of the West Bank and called on supporters of the movement in Israel to join the strike. Thus far, there have been reports of clashes between Israeli security forces and several hundred protesters at the Damascus Gate in Jerusalem’s Old City, but there have been no reports of larger demonstrations. Meanwhile, the Israeli government extended the nighttime curfew in the city of Lod until at least 20 May, due to the heightened threat of ethnic unrest.

Earlier on 17 May, unidentified individuals fired at least six rockets from the area of the Lebanese village of Aadaysit Marjaayoun – located approximately 40 km (25 mi) east of Tyre — toward the Israeli kibbutz of Misgav Am, located on the border with Lebanon approximately 115 km northeast of Haifa. Reports indicate that all the rockets landed on the Lebanese side of the border. The IDF stated that its artillery forces fired toward the source of the rockets. There were no reports of casualties in the attack. Israeli forces also shot down a drone near the border with Jordan, but it is unclear if the drone was launched from Jordan or nearby Syria.
