Turkish intelligence chief Ibrahim Kalin met with Hamas leaders in Turkey to discuss aid delivery to Gaza and oppose any new efforts to occupy or annex Palestinian territory. Hamas expressed willingness to reach a comprehensive prisoner exchange agreement and called for an Israeli withdrawal from Gaza. The United Nations has warned of a severe humanitarian crisis in Gaza, and Israel has vowed to maintain its blockade to pressure Hamas to release hostages. Since March 18, Israel's renewed assault on Gaza has resulted in the deaths of at least 1,691 people.
