Israel has hit out at the central Gaza strip for the second time this week, in what is termed as raids.
According to Israel’s military its fighter jets attacked an underground complex used to produce rocket engines.
Although there is no immediate report of casualties, witnesses say the attacks damaged several homes in the al-Bureij refugee camp in central Gaza.
Earlier in the night, a rocket fired from Gaza struck southern Israel, causing slight damage to a house but no injuries, Israeli police said. Four more rockets were also fired from Gaza, the Israeli military said, following its raids on the besieged coastal enclave, but were intercepted by air defence systems.
No Palestinian faction claimed responsibility for the rocket launches.
In a statement, Hamas, the group that administers Gaza, said Israel’s bombing will only encourage Palestinians to “resist the occupation and step up their support for Jerusalem and its people”.
A surge of violence in Israel and the occupied Palestinian territory has raised fears of a slide back to a wider conflict, after last year’s 11-day Israeli assault on Gaza, in which more than 250 Palestinians in Gaza and 13 people in Israel were killed.
In March, Israeli forces killed at least 29 Palestinians in raids on the West Bank as 14 people in Israel were killed in street attacks.
