Qatar announced early Monday that an agreement has been reached to release an Israeli civilian hostage and allow Palestinians to return to northern Gaza, easing the first major crisis of the fragile ceasefire between Israel and Hamas.

The release of hostages in exchange for convicted terrorists under Israel’s ceasefire deal with Hamas stirs profound emotions, reigniting debates over justice, security and national unity.

Hamas released four Israeli hostages in Gaza early Saturday in exchange for 200 Palestinian prisoners to be released later in the day. It was the second release to occur as part of the ceasefire agreement that began last weekend. Israel followed with the release of 200 Palestinian prisoners.
