The U.N. envoy to the Mideast says it�s the �last chance� to prevent an all-out conflict between Israel and Gaza terrrorist.

Nikolay Mladenov said on Monday that the �risk of war remains imminent,� a week after a cease-fire between Israel and Gaza�s Hamas rulers ended the worst fighting since a 2014 war.

The spate of violence killed 25 Palestinians, most of them terrorists, and four Israeli civilians.

Mladenov, inaugurating a solar power plant for a Gaza hospital, said parties must �consolidate the understandings� of the cease-fire.

The deal, mediated by Egypt, Qatar and the U.N., promises to let in fuel and humanitarian aid and ease the movement of people from the blockaded territory.

A Qatari cash infusion, meant for thousands of needy families as part of the cease-fire understandings, arrived Monday.
