'No further time to lose'
Israeli military spokesman Rear Admiral Daniel Hagari said his country was "ready to foil any threat in real time" but added that he was "not familiar" with reports that Iran was expected to launch an attack in the next 24 hours.
Israel's defence minister Yoav Gallant said the country had strengthened defences and organised "offensive options" as "threats from Tehran and Beirut may materialise".
Washington and the four European nations meanwhile intensified their calls for a ceasefire in Gaza, regarding the conflict sparked by Hamas' October 7 attack on Israel as the root cause of the tensions in the Middle East.
They backed a call by Biden and the leaders of Egypt and Qatar for renewed talks between Israel and Hamas this Thursday, "and stressed there is no further time to lose".
They also called for "unfettered" delivery of aid to devastated Gaza.
The pressure to bring an end to the fighting in the Gaza Strip and for Hamas to release its hostages came as the militant group's armed wing said it had killed one Israeli captive and wounded two more in "incidents".
The Ezzedine Al-Qassam Brigades said in a statement that two of its fighters "assigned to guard" the hostages had fired at them in "two separate incidents" and that a committee had been formed to investigate.
Hamas has urged mediators to implement a truce plan earlier presented by Biden instead of holding more talks.
But Israel has accepted the invitation from the United States, Qatar and Egypt to send negotiators.
"The reason we're doing that is to finalise the details of the implementation of the framework agreement," Israeli government spokesman David Mencer told a news conference.
