GAZA, May 13 (Xinhua) -- The United Nations peace envoy Nikolay Mladenov on Monday called on Israel and Palestinian factions to intensify their efforts to stabilize the cease-fire, which was brokered by Egypt, the United Nations and Qatar.

"We hope that all parties will abide by calm, so as not to collapse the calm in Gaza and to be able to proceed with the implementation of humanitarian support projects," Mladenov told the reporters in a news conference, while he is following up the solar energy project carried out by the World Health Organization at Nasser hospital in southern Gaza strip.

"We need the cooperation of all, including the Palestinian Authority, Egyptians and Israelis, to improve the lives of Palestinians in Gaza so that they have hope for a better future," Mladenov said.

He noted that Gaza was close to a real war last week, voicing his worries about the situation and vowing to do his best to restore calm between Israel and Palestinian factions.

"No one wants to invoke war because it will bring destruction to Israelis and Palestinians," he added.

Qatar's position is very important to stabilize the truce and the Gaza, and the United Nations has worked well to ease the suffering of Gaza people and to make a breakthrough in lifting the blockade, he added.

The UN envoy said that he is focusing now on creating temporary jobs in cooperation with the World Bank and the United Nations Development Program.

A meeting will be held Monday between Mladenov and Islamic Hamas movement in Gaza to discuss mechanisms to strengthen the cease-fire understandings with the Palestinian factions in the Gaza Strip.

On Friday, the office of Hamas politburo chief Ismail Haniyeh said in a press statement that Haniyeh spoke with the UN envoy on telephone and discussed the implementation of the understandings that were reached with Israel.

In a related context, the Qatari Gaza reconstruction committee began distributing cash aid to more than 100,000 people through local post offices.

Earlier on Monday, the Qatari envoy Mohammed al-Ammadi arrived in the Gaza Strip to supervise the distribution of financial aid.

Egypt, the United Nations and Qatar brokered a new cease-fire agreement between Palestinian factions and Israel to end the round of tension.

The cease-fire agreement was reached last Monday between Israel and the Palestinian factions after three days of tensions.
