An explosion went off Tuesday morning near a convoy carrying Palestinian Prime Minister Rami Hamdallah, who is visiting the Gaza Strip.
The Palestinian Authority initially blamed Hamas for the explosion, which it said targeted Hamdallah's convoy.
Later Tuesday, however, Hamas leader Ismail Haniyeh spoke with Hamdallah and the two agreed that Israel and its collaborators are responsible.
The Palestinian leaders also agreed that General Tawfiq Abu Naim, head of Gaza's Interior Ministry, will lead the investigation into the incident.
According to reports, several people were lightly wounded in the incident. Gaza's Interior Ministry said several suspects have been arrested and a manhunt is underway.
Hamdallah entered the Strip at 10 A.M. with Palestinian intelligence chief Majid Faraj for a visit that was planned five months ago.
The purpose of the visit was to open a waste treatment plant that the Palestinian Authority helped finance.
Hamdallah also met with senior Hamas officials on the subject of the stalled reconciliation talks between Hamas and the PA.
The explosion went off when Hamdallah's convoy had driven some 200 meters into the Gaza Strip after entering through Erez Crossing on the Israeli side.
According to Arab media, Hamdallah and Faraj were not injured. Hamdallah's convoy left the Strip shortly after the incident.
Following the assassination attempt, Hamdallah said he is still committed to Palestinian unity. He added that three cars were damaged as a result of the blast.
"I will return to Gaza despite what happened today and I call on Hamas to allow the government to effectively control the Gaza Strip," Hamdallah said, adding: "What happened today will not stop us from continuing reconciliation efforts."
"Despite what happened we will continue to build our institutions and we will press on with the reconciliation efforts with the help of Egypt," Hamdallah said.
"I call on Hamas and all other factions to take part in the national Palestinian council that will convene in April because this is a critical phase for the Palestinian people."
