Sirens sounded in Israel at various locations on a day of heightened tension following demonstrations in the coastal enclave and the occupied West Bank as Palestinians protested at U.S. President Donald Trump's announcement on Wednesday that he was recognising Jerusalem as Israel's capital.
Two rockets launched at Israel from the Gaza Strip fell short inside the Palestinian enclave earlier in the evening and a third, fired later, landed in an open area in Israel causing no casualties or damage, an army spokeswoman said.
Gaza residents said there were no casualties from the Israeli attack and that two unmanned lookout posts were hit.
A Jihadist Salafi group in Gaza called the Al-Tawheed Brigades - which does not heed the call from the enclave's dominant force, Hamas, to desist from firing rockets - claimed responsibility for the launches.
During the Gaza war in 2014, Israel's Iron Dome rocket interceptor system largely protected the country's heartland from thousands of rocket barrages fired by terrorists.
