MOSCOW, March 24 (Reuters) - The Kremlin on Tuesday, when asked about a Reuters report that Russia was postponing a plan to boost long-term fiscal reserves, said that the issues were being worked out and that they were being discussed at President Vladimir Putin's meetings on the economy.

Reuters' sources said on March 23 that the government would now postpone a plan to boost long-term fiscal reserves due to the oil price spike triggered by the Iran war.

March 24 (Reuters) - Airstrikes targeting a site belonging to Iraq's Shi'ite Popular Mobilization Forces in the western province of Anbar killed at least 15 fighters, including the PMF's Anbar operations commander, and wounded 30 others, security and health sources told Reuters early on Tuesday.

The PMF confirmed in a statement the death of its Anbar commander, Saad al-Baiji, and 14 of his companions. It accused the United States of carrying out the attack, saying a U.S. airstrike targeted a command headquarters while personnel were on duty.

DUBAI, March 24 (Reuters) - Iranian police arrested 466 people accused of online activities aimed at undermining national security, state media reported on Tuesday, in one of the biggest security sweeps since the start of the war with Israel and the United States.

JERUSALEM, March 24 (Reuters) - U.S. President Donald Trump appears to be determined to reach a deal with Iran aimed at ending hostilities in the Middle East, three senior Israeli officials said on Tuesday.

The officials, speaking on condition of anonymity, said that they viewed it is unlikely that Iran would agree to U.S. demands in any new round of negotiations, which broke down on February 28 with the launch of the U.S.-Israeli war on Iran.

Those U.S. demands were likely to include curbs on Iran's nuclear and ballistic missile programmes.

March 24 (Reuters) - The United States will continue its strikes on Iran, with the pause applying only to attacks on Tehran's energy sites, Semafor reported on Monday, citing a U.S. official, during what President Donald Trump has described as "productive" talks with unidentified Iranian officials.

Earlier on Monday, Trump had postponed for five days a plan to hit Iran's energy grid. Iran later denied that it had engaged in negotiations with the United States.

"The stop on attacks for five days is only on their energy sites," a U.S. official told Semafor.

WASHINGTON/JERUSALEM/TEL AVIV, March 24 (Reuters) - Iran launched multiple waves of missiles at Israel, the Israeli military said, after U.S. President Donald Trump postponed a threat to bomb the Islamic Republic's power grid because of what he described as productive talks with Iranian officials.

The missiles triggered air raid sirens in parts of Israel, including Tel Aviv where blasts from interceptions were heard. In one attack, homes in northern Israel were damaged by falling debris following an interception. No deaths were reported.

Israel said on Tuesday that its military would take control of south Lebanon up to the Litani River, around 30 kilometres (20 miles) from the border, as deadly strikes pounded the country.

In the latest unprecedented step by Lebanese authorities since a new war erupted between Israel and Hezbollah, Beirut's foreign ministry declared the Iranian ambassador persona non grata, giving him until Sunday to leave the country.

Hezbollah strongly objected to the move, calling on the government to reverse it.
