With U.S. envoy Hady Amr set to arrive in Israel on Friday for de-escalation talks with Israeli, Palestinian and UN officials, Israeli officials are concerned the U.S. intervention will lead to increased pressure to stop their military operation.

Driving the news: Fighting continued overnight, with the Israeli military massing forces along the frontier with the Gaza Strip and briefing reporters about ground forces entering the fight. Anticipating a ground invasion, Hamas sent its elite forces to their defensive tunnels. The Israeli forces instead began to bomb those tunnels and did not cross into Gaza, Israeli officials say.

• It's unclear how many Hamas fighters were killed in the bombardment.
• The air war between Israel and Hamas continued, with Hamas firing 200 rockets toward Israel overnight and the Israeli air force striking in Gaza.
• At least 120 Palestinians have been killed in the fighting, including 30 women and children, Gaza health officials said on Friday morning. Seven Israelis have been killed, including one soldier and one child.

What's next: It's unclear if Amr will meet with Prime Minister Benjamin Netanyahu or other senior Israelis.

• The Israeli government had hinted to the U.S. that it might be better to hold the visit at a later stage, U.S. and Israeli officials say. Israel has said it's not yet ready to seek a ceasefire.
• Ahead of Amr’s visit, Secretary of State Tony Blinken spoke with both Netanyahu and Palestinian President Mahmoud Abbas — the first call between Abbas and a cabinet-level official since Biden assumed office.

The UN Security Council is expected to meet on Sunday for an open meeting on the situation in Gaza.

• Behind the scenes: China, Norway and Tunisia had been pushing for the meeting to take place on Friday but the U.S. blocked those efforts, Israeli and U.S. officials say.
• Israel has asked the Biden administration to block any measures at the UN since the fighting began on Monday, and the U.S. has blocked at least two attempts by other members of the council to publish a statement on the situation. Israeli officials say it became impossible for the U.S. to continue to prevent a meeting.
• Blinken said on Thursday that holding the meeting later “will give some time for the diplomacy to have some effect and to see if, indeed, we get a real de-escalation and can then pursue this at the United Nations in that context."
