Hamas released six more hostages Thursday afternoon, adding to the two released earlier in the day and bringing Thursday's total to eight.

Israel released another group of Palestinian prisoners on Thursday, maintaining its end of the agreement that has pushed a tenuous cease-fire into its eighth day.
The truce is currently scheduled to end on Friday, but negotiators are working to continue it. Israel has promised to resume its fight against Hamas when the agreement does end.
Hostage release agreements may become more difficult going forward, as Hamas is expected to make greater demands to secure the release of civilian men and soldiers.
Some 140 people are thought to still be held hostage by Hamas.
In previous days, Hamas has released 10 hostages in exchange for 30 Palestinian prisoners held by Israel.
Thirty Palestinians were again released on Thursday, according to a Qatari officials assisting in the negotiations.

U.S. Secretary of State Antony Blinken is back in Israel for the third time since the start of the war. He's expected to press Israeli leaders to dial back the military's bombardment of Gaza.

Blinken said the U.S. would prefer a longer cease-fire.
Meanwhile, the Israel Defense Forces warned Gazans not to return to Northern Gaza during the cease-fire. IDF says the area remains a "war zone" and Gazans should remain in Southern Gaza.
