This was at least the third time in the last two weeks that Israeli forces struck targets in Gaza, according to army statements, in violation of the ceasefire in the Israeli war on Gaza.
The occupation army said it "struck the launch site from which the projectile was fired, as well as an additional launch site in the area."
The first phase of the Gaza truce, which went into effect on January 19 after 15 months of devastating war, is due to expire in early March, with no agreements yet on a subsequent phase that could cement the ceasefire.
Prime Minister Benjamin Netanyahu on Sunday said that Israel was prepared to resume the war "at any moment", after suspending the release of Palestinian prisoners under the truce deal.
Since the ceasefire began, Hamas have released 25 living Israelis in exchange for more than 1,100 Palestinian detainees freed from Israeli jails.
Hamas has warned that Israel's decision could jeopardise the "entire agreement".
