The FBI has arrested a suspect in Louisiana, identified as Mahmoud Amin Ya'qub Al-Muhtadi, who allegedly participated in Hamas' Oct. 7, 2023 attack on Israel.

The region celebrated early last week that part of the ceasefire’s first phase was successful.

While the ceasefire has held, the prospect of peace in the region is unstable and remains touch-and-go.

Israel has reopened two crossings in Gaza, while the key Rafah crossing will stay closed to the movement of people until further notice.

Federal prosecutors arrested a man living in Lafayette who they say participated in the October 2023 attacks on Israel and later traveled to the U.S. on an illegal visa, according to newly unsealed documents obtained by the New York Times.

After 738 days in Hamas captivity, the final 20 living hostages crossed the border from Gaza back into Israel on Monday.
