Pro-Iran hackers have threatened to release emails supposedly stolen from people connected to President Donald Trump, according to a news report, a move that federal authorities call a "calculated smear campaign."

The United States has warned of continued Iranian cyberattacks following American strikes on Iran's nuclear facilities and the threats those could pose to services, economic systems and companies.

Hamas suggested Wednesday that it was open to a ceasefire agreement with Israel, but stopped short of accepting a U.S.-backed proposal announced by President Donald Trump hours earlier, insisting on its longstanding position that any deal bring an end to the war in Gaza.

Trump said Tuesday that Israel had agreed on terms for a 60-day ceasefire in Gaza and urged Hamas to accept the deal before conditions worsen. The U.S. leader has been increasing pressure on the Israeli government and Hamas to broker a ceasefire, and hostage agreement and bring about an end to the war.

Dozens of international charities and non-governmental organizations, including Oxfam, Save the Children and Amnesty, called Tuesday for an Israeli and U.S.-backed aid mechanism for Gaza to disband over repeated incidents of chaos and deadly violence against Palestinians heading toward its sites.

At least seven Palestinians were killed seeking aid in southern and central Gaza between late Monday and early Tuesday.

A man suspected of gathering information on Jewish locations and individuals in Berlin for Iranian intelligence, possibly with a view to carrying out attacks, has been arrested in Denmark, German prosecutors said Tuesday.

A Ukrainian drone struck a Russian industrial plant some 1,300 kilometers (800 miles) from Ukraine, a local official said Tuesday, after Ukraine President Volodymyr Zelenskyy prioritized the weapon's development and Russia pounded Ukraine with a monthly record of drones in June.

Both sides in the more than three-year war following Russia's February 2022 invasion of its neighbor have raced to improve drone technology and enhance their use on the battlefield. They have deployed increasingly sophisticated and deadlier drones, turning the war into a testing ground for the new weaponry.

A ceasefire between Iran and Israel has not ended the threat of cyberattacks from hacking groups supportive of Tehran, the FBI and federal cybersecurity officials warned Monday.

In a public bulletin, the authorities warned that hacking groups affiliated with or supportive of Tehran may still seek to disrupt or disable critical infrastructure systems in the U.S. such as utilities, transportation and economic hubs. Hackers may also target defense contractors or other American companies with ties to Israel, the agencies said.

A heat wave covered much of Europe on Monday, with a record-hot first day of play at Wimbledon and high winds fanning forest fires in Turkey.

Iraq's top court was set to resume work Monday after nine judges who had tendered their resignations in recent weeks returned to work following the retirement of the court's president and the appointment of a successor.

Iraq's Supreme Judicial Council announced Sunday the retirement of the head of the Federal Supreme Court, Judge Jassim Mohammed Abboud Al-Amiri, citing "health reasons." The Council nominated Judge Mundher Ibrahim Hussein, deputy president of the Federal Court of Cassation, to assume the position, and Hussein was appointed by presidential decree on Monday.

President Donald Trump signed an executive order on Monday ending many U.S. economic sanctions on Syria, following through on a promise he made to the country's new interim leader.

White House press secretary Karoline Leavitt said the move was designed to "promote and support the country's path to stability and peace."
