The Hamas militant group has condemned the Gaza explosion that targeted the convoy of visiting Prime Minister Rami Hamdallah.
There was no claim of responsibility, but the official Wafa news agency said the West Bank-based Palestinian Authority held Gaza's Hamas rulers accountable.
Three of the vehicles in his convoy were damaged, their windows blown out.
Member of Palestine Liberation Organization Ahmad Majdlani said that the Gaza Strip issue is political in the first stance and not a humanitarian or relief, and Washington knows well that the reasons behind the coastal enclave are tied to the Israeli blockade.
Regarding the convening of the national council, Al-Ahmad said that Hamas was not invited to attend because it would be held with its current formation and Hamas remains outside this shape due to the continued division. "The challenge will be determining which ideas can be realistically implemented in light of the fact that the Palestinians of Gaza continue to suffer under the authoritarian rule of Hamas", he added.
It is Hamdallah's second visit to the Gaza Strip since the signing of an Egyptian-brokered "reconciliation" agreement between the West Bank's governing Fatah faction and Gaza's Hamas rulers late a year ago.
Mr Hamdallah went on to appear at an event to open a water treatment plant.
"The attack against the government of consensus is an attack against the unity of the Palestinian people", said Nabil Abu Rdainah, a spokesman for Palestinian President Mahmoud Abbas. His convoy later left the territory.
He was also met with senior Hamas officials to discuss reconciliation talks between Hamas and the PA.
