Hamas authorities and Israeli military reports said Israel conducted air assaults in central Gaza before daybreak on Thursday after a missile fired from the Palestinian enclave hit in Israel.
As per witnesses, Hamas, the Islamist party that administers the encircled region, employed two training sites and there were no casualties.
The Israeli military claimed in a statement that Israeli aircraft attacked a security station and portions of an underground complex used to manufacture rocket engines.
A missile discharged from Gaza hit southern Israel earlier, causing minor destruction but no casualties, according to authorities. There was no claim of accountability for the attack, which is the second in numerous days.
An increase in aggression in Israel and the seized Palestinian territory has fueled fears of a return to more widespread conflict.
Nearly 30 Palestinians have been slain by Israeli troops in West Bank operations since March, and 14 Israelis have been killed in a wave of devastating Arab street attacks.
Hamas claimed in a statement that Israel's bombardment will only embolden Palestinians to reject the occupation and increase their allegiance to Jerusalem and its residents.
The worsening situation in Jerusalem has alarmed United Nations Secretary-General Antonio Guterres.
According to a statement sent by his office in New York, he was in communication with the parties to urge them to do everything they can to decrease tensions, and avoid violent actions and discourse.
Conflicts in Jerusalem's Old City, notably at the Al-Aqsa mosque area, also known as Temple Mount by Jews, raise the potential of a repeat of last year's 11-day Israel-Gaza conflict, which killed over 250 Palestinians in Gaza and 13 Israelis.
This year's tensions have been exacerbated by the effect of the Muslim holy month of Ramadan falling on the same day as the Jewish holiday of Passover.
Palestinians claim that by admitting more Jewish worshippers into the holy compound, Israel is breaking a centuries-old norm that allows non-Muslims to attend but not pray.
Israeli politicians have stated that all religions will be able to worship freely in Jerusalem. Al-Aqsa is Islam's third sacred place, as well as the site of two ancient Jewish temples.
Palestinians expect East Jerusalem to be the capital of a future state, with its Muslim, Jewish, and Christian sacred sites.
After capturing the territory in a 1967 conflict, Israel claimed East Jerusalem in a move that was not recognized internationally. Israel considers all of Jerusalem to be its everlasting capital.
