According to the Israeli military, the attack was carried out due to a drone being spotted flying into the Gaza Strip from Israel. Such drones have been seen before in attempts to smuggle weapons into the Palestinian area.
A 44-year-old man was killed in an Israeli attack on southern Gaza Strip, reports the Palestinian healthcare there.
Israel reserves the right to open fire on individuals who approach their forces or violate the ceasefire terms, for example, by staying in areas where it is not permitted.
The Islamist movement Hamas, on the other hand, has threatened to delay further releases of hostages, as it believes Israel is violating the terms in various ways.
According to healthcare sources in Gaza, at least 92 Palestinians have been killed and more than 800 injured in Israeli attacks during the three weeks that the first phase of the ceasefire has lasted.
