A Palestinian man has been killed in an Israeli missile attack in the first death since the end of a six-month-old ceasefire between Israel and Hamas.
Ali Hijazi, 22, and two other men who were wounded were members of the al-Aqsa Martyrs Brigade, eyewitnesses said on Saturday.
The air strike targeted a group of militants firing rockets towards Israel,an Israeli military official said.
The attack in Beit Lahiya in the northern Gaza Strip came a day after the end of the ceasefire.
Sherine Tadros, Al Jazeera's correspondent in Gaza, said that Israeli security sources have told her that they carried out an air strike in the northern Gaza Strip.
"The [Israeli] military told us that six projectiles have been launched from the Gaza Strip towards southern Israel," she said.
"This kind of sporadic violence has been taking place here in Gaza within the last six weeks or so.
"But it is extremely significant that it is coming as the first air strike after the expiration of the truce between Palestinian factions and Israel on Friday.
"This is coming as very sad news for the people here who once again find themselves in the position they were in before the ceasefire, in terms of this almost daily aggression by Israel and very uncertain times in terms of what will happen next.
"From the Israeli side they have said that ... as long as there is peace from the Palestinian side they will respond with peace. But if there is aggression by Palestinian factions, they will fight back with force."
A ceasefire agreed to in June officially ended in Gaza at daybreak on Friday, after Hamas said they would not renew the shaky ceasefire.
Hamas blamed Israel for the failure of the ceasefire, saying that they had not lived up to their obligations under the deal by continuing a blockade of the Gaza Strip.
