Iran's army on Thursday added 1,000 drones to its combat regiments as its chief vowed a "crushing response" to any attack, state television reported, after the United States moved a strike force into regional waters.

"In accordance with the threats we are facing, maintaining and enhancing strategic advantages for rapid combat and a crushing response to any invasion... is always on the army's agenda," Iran's army commander Amir Hatami said, cited by state television.

The Kremlin said on Thursday there was still room for negotiations in the standoff between ally Tehran and Washington, after U.S. President Donald Trump threatened new military strikes on Iran.

"It is clear that the potential for negotiations is not exhausted," spokesman Dmitry Peskov told journalists, adding: "any use of force can only create chaos in the region and lead to very dangerous consequences."

Turkey will offer to help resolve tensions between Washington and Tehran when Iran's top diplomat visits, a foreign ministry source said Thursday a day ahead of the visit.

"Turkey is ready to contribute to resolving the current tensions through dialogue," Turkish Foreign Minister Hakan Fidan was to tell his counterpart Abbas Araghchi when the pair meet on Friday, the source said.

Iran's foreign minister warned Wednesday its forces would respond immediately and forcefully to any U.S. military operation after President Donald Trump declared time was running out to avoid one, but did not rule out a new deal on Tehran's nuclear program.

The Islamic republic's top diplomat Abbas Araghchi warned its forces have their "fingers on the trigger" to "powerfully respond" to any U.S. strikes, but also used language strikingly similar to Trump's to describe a possible agreement to defuse the stand-off through a new nuclear deal.

The European Union on Thursday announced sanctions on 15 Iranian officials, including top commanders and officials of the paramilitary Revolutionary Guard, over Tehran's deadly crackdown on nationwide protests.

Six Iranian organizations, including bodies responsible for monitoring online content in Iran, were also included in the sanctions list.

Prime Minister Benjamin Netanyahu on Wednesday warned Israel's enemies that they would pay a heavy price if they attacked, speaking at the funeral for the last hostage to be recovered from Gaza.

Israel has pledged an investigation after two Italian security officers were held up by an Israeli soldier with an automatic weapon in the occupied West Bank.

An international media association expressed disappointment after Israel's supreme court again postponed ruling on a petition seeking free and independent press access to Gaza, in a statement sent to media on Wednesday.

Since the outbreak of the Gaza war in October 2023, triggered by an attack on Israel by the Palestinian militant group Hamas, the Israeli government has barred foreign journalists from independently entering the blockaded territory.

Iraq's main candidate for the premiership, Nouri al-Maliki, on Wednesday denounced Washington's "blatant interference", after President Donald Trump warned that he would end all support to the country if Maliki took the post.

"We categorically reject the blatant American interference in Iraq's internal affairs," Maliki said on X, adding that "we consider it a violation" of Iraq's "democratic system" after the 2003 U.S.-led invasion.

Syrian President Ahmad al-Sharaa will meet Russian counterpart Vladimir Putin in Moscow on Wednesday, as the Kremlin seeks to secure the future of its military bases in the country.
