The U.N.'s top Mideast envoy says Palestinians in Gaza are growing ever more desperate and unless "radically more" is done to address the situation, it is only a matter of time before there is another escalation of violence.

Nickolay Mladenov told the Security Council on Wednesday that May saw the biggest escalation of violence in Gaza since 2014 and that those incidents threaten the current ceasefire.

He said the Quartet of Mideast mediators — the U.N., U.S., European Union and Russia — are finalizing a report on the impediments to a two state solution and how to move forward.

He also said a number of countries will meet in Paris within "a matter of days" in hopes of reviving the Israeli-Palestinian peace process.
