GAZA CITY (Ma'an) -- An Israeli airstrike killed three Palestinians in the northern Gaza Strip on Thursday evening, the health ministry said, bringing the death toll to 19 on the second day of fighting.
Brothers Tareq Jamal Naser, 16, and Oday Jamal Nasser, 14, as well as Fares al-Bassiouni were killed when Israel bombed their home in Beit Hanoun, the ministry said.
The brothers' father and three children were among six injured in the explosion. Witnesses said a fire broke out affecting a nearby mosque after the bombing.
Israel's army said it had hit around 70 rocket-launching sites in the course of an hour on Thursday evening, as deadly violence continued since Israel assassinated a Hamas commander on Wednesday.
The aerial bombardment set off earth-shaking thuds and fireballs in the dark sky and were met with screeches of Palestinian rocket fire launched from the outskirts of Gaza City towards southern Israel.
One of the sites targeted by Israel was an electricity generator that supplied the house of Hamas's prime minister in Gaza, Ismail Haniyeh. It was unclear whether he was at home at the time.
Witnesses told Ma'an violent explosions across Gaza City's Sheikh Radwan neighborhood set a high-rise building ablaze, with flames lighting Gaza's sky. Several injured, including women, were brought to Gaza's Al-Shifa hospital, a Ma'an correspondent said.
Airstrikes also hit an open area east of Gaza City, and four areas near Rafah in south Gaza.
Witnesses said Israeli planes hit the marine police headquarters in Deir al-Balah, which has been destroyed repeatedly in Israeli airstrikes. Sites in Khan Younis were also hit.
