U.N. officials said that real progress was being made Sunday with the aid being allowed into Gaza
Eri Kaneko, a spokesperson for the U.N.'s Office for the Coordination of Humanitarian Affairs, said supplies of cooking gas had entered Gaza for the first time since March. Other aid moving through include flour, fruit and meat.
U.S. President Donald Trump, who pushed to clinch the ceasefire deal, is expected to arrive in Israel Monday morning. He will meet with families of hostages and speak at the Knesset, Israel's parliament, according to a schedule released by the White House.
Trump will then continue on to Egypt, where the office of Egyptian President Abdel-Fattah el-Sissi has said he will co-chair a "peace summit" on Monday with attendance by regional and international leaders.
Gaza's Hamas-run Interior Ministry has deployed thousands of police in areas the Israeli military withdrew from after the ceasefire took effect.
