Israeli fire killed three people near a ceasefire line in Gaza on Monday, medics said, with U.S. envoys expected in Israel to try to push forward the fragile truce that faced its gravest test so far over the weekend.

A Gazan man accused of being involved in the October 7 attacks on southern Israel two years ago has been arrested in Louisiana, according to justice officials.

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

The Israeli military launched an attack on Gaza on Sunday, Israeli media and residents reported, dimming hopes that a U.S.-mediated ceasefire would lead to lasting peace in the enclave as Israel traded blame with Palestinian militant group Hamas.

Mahmoud Amin Ya'qub al-Muhtadi allegedly took part in the attack on Israel and lied on a visa application, court documents say.

The attacker is seen striking the 55-year-old woman with a large wooden stick during the assault in the West Bank village of Turmus Ayaa.
