The Israeli military says its aircraft hit a Palestinian rocket squad in Gaza just after the militants fired rockets at Israel. Palestinian security says three people were wounded.
The airstrike took place in northern Gaza, the most frequent launching area for rockets. Militants fired four rockets at Israel on Tuesday, the military said. There were no reports of damage or casualties.
Since Israel called off its offensive in Gaza in late January, and the Islamic Hamas rulers of Gaza also declared a cease-fire, more than 100 rockets have been fired at Israel, according to the military.
Israel routinely retaliates by bombing smuggling tunnels along the Gaza-Egypt border and targeting Hamas weapons stores. Airstrikes at militants are less frequent.
