Palestinian militants fired a rocket on Israel from the Gaza Strip Wednesday, prompting Israel's premier to hold Palestinian president Mahmud Abbas responsible for such attacks.
Abbas condemned the rocket fire, which Israeli officials said hit the Eshkol region without causing any casualties or damage.
The attack came just over a week after the Palestinians formed a unity government for both Gaza and the West Bank, as part of efforts to end years of division.
From 2007, when Hamas drove Abbas's forces from Gaza, the territory was ruled by Islamist movement Hamas, which Israeli routinely blamed for all attacks on the Jewish state.
Now, a spokesman for Prime Minister Benjamin Netanyahu said Abbas, who heads the unity government, is responsible for rocket fire from Gaza.
"Abbas is responsible and accountable for rockets that are fired at Israeli towns and cities by terrorists in the Gaza Strip," Ofir Gendelman wrote on Twitter.

Another Netanyahu spokesmen released a statement demanding that Abbas disarm "terrorist" organisations in Gaza.
"Abbas claims that the new Palestinian government honours all previous commitments. So why has he not disarmed the terrorist organisations in Gaza as he is obligated to do," Mark Regev asked.
Reacting to the incident, the Palestinian presidency issued a statement Wednesday evening that "condemns the rocket fire and calls for honouring past agreements."
The new government of independent technocrats agreed on between Abbas's Fatah party and Hamas, has said it will respect past agreements with Israel, and given assurances that it will recognise Israel and renounce violence.
Hamas refuses to recognise Israel and is pledged to armed struggle against the Jewish state.
Some 140 projectiles fired by militants in the Gaza Strip have hit southern Israel since the start of 2014, the military says.
On June 1, two rockets from Gaza hit Israel, prompting retaliatory raids by the Israeli air force.
