Khan Younis – Ma'an – Israeli warplanes launched attacks across the Gaza Strip early Friday, destroying several buildings.
Ma’an correspondent in Khan Younis said aircraft bombed three targets in the area, including a site housing Hamas' Al-Aqsa TV network.
In Gaza City, warplanes targeted the Daloul cheese and diary factory in the Sabra neighborhood. Houses were damaged nearby.
Aircraft fired two missiles at a police station in the Nusseirat refugee camp in addition to other sites in central Gaza, including a telecommunications company.
Dr Muawiya Hassanein, director of ambulance services in the Gaza Health Ministry, said that three children were hurt in one of the blasts.
The children were injured in the strike targeting the Daloul factory, he said. Several homes around the facility were damaged, as flying debris from the strike caused mild to moderate wounds and breaks, he added.
The injured were identified as one-year-old Malak Mas'ad Al-Arabid, her four-year-old brother Sa'd, and cousin Abdul Rahman Sarsur, 11.
In other areas, Hassanein said, "only material damage" had resulted from the strikes. In accordance with an emergency plan developed for renewed Israeli attacks, ambulances were mobilized throughout Gaza in anticipation of casualties.
Palestinians across the coastal enclave said dozens of Israeli aircraft were spotted overhead.
An Israeli military spokesman said the warplanes targeted two weapons manufacturing facilities; one in the north, one in central Gaza, and two weapons storage facilities in the south.
Earlier, Israeli officials reported that Palestinian militias fired a homemade rocket into Israeli territory from Gaza. No one was injured.
Late Thursday, Israeli warplanes dropped leaflets on areas of Gaza bordering Israel warning Palestinians not to approach the frontier.
