WASHINGTON, April 15 (Reuters) - Reports that the White House has requested a ceasefire in the Iran war are wrong, press secretary Karoline Leavitt told reporters on Wednesday but added that discussions about a second round of talks with the Iranians were ongoing and productive.

Speaking at a White House press briefing, Leavitt said any fresh talks would likely be in Pakistan again as it has emerged as the "only mediator" in the effort to end the U.S.-Israeli war on Iran.

WASHINGTON, April 15 (Reuters) - A majority of the U.S. Senate backed President Donald Trump's military campaign against Iran on Wednesday, voting to block a Democratic-led resolution aiming to stop the war until hostilities are authorized by Congress.

As voting continued, the tally was 51-47 to block the war powers resolution, as almost all of Trump's fellow Republicans voted against it.

BEIRUT April 15 - Brothers Ali and Wael Sabbagh stood facing the remains of the building that contained their family home for more than 50 years.

The site was pounded into rubble by Israeli strikes last week in an attack that killed their mother, brother, and the family's helper.

Sudanese pilot Mohamad Daafallah grins as he shakes hands with passengers after their landing at Khartoum Airport, exactly three years after it was bombed to shreds during the outbreak of war in Sudan.

The airport was one of the last footholds of the rival paramilitary Rapid Support Forces (RSF), where battles raged as the army launched an offensive last year to retake Khartoum.

DUBAI, April 15 (Reuters) - Iran could consider allowing ships to sail freely through the Oman side of the Strait of Hormuz without risk of attack as part of proposals it has offered in negotiations with the United States if a deal is clinched to prevent renewed conflict, a source briefed by Tehran said.

The war has resulted in the largest-ever disruption of global oil and gas supplies due to Iran's interruption of traffic through the strait, which handles about 20% of the world's oil and liquefied natural gas flows.

April 15 (Reuters) - The Kremlin's spokesman was quoted as saying on Wednesday that the United States had rejected its proposal that Russia take all of Iran's enriched uranium out of the country as a way to help resolve the Middle East conflict.

Russia first proposed last Junethat it take control of Iran's uranium stock, but no action was taken. According to news reports, Russia issued the proposal again this week.

IMF chief Kristalina Georgieva warned Wednesday of difficult times ahead for the global economy if war in the Middle East is unresolved and oil prices stay high, adding that inflation risks could seep into food prices.

"We must brace for tough times ahead" if the conflict persists, she told reporters at a press briefing during the International Monetary Fund and World Bank's spring meetings in Washington.

The gathering brings government and financial leaders to the US capital this week, with policymakers looking to limit economic fallout from the war.

April 15 (Reuters) - The war in Sudan entered its fourth year on April 15 overshadowed by other regional and global turmoil, despite having created what the United Nations calls the world's worst humanitarian crisis.

WHO IS FIGHTING?

The war pits the Sudanese army, led by General Abdel Fattah al-Burhan, against the Rapid Support Forces, a paramilitary group led by General Mohamed Hamdan Dagalo.

April 15 (Reuters) - United Nations experts on Wednesday condemned Israel's bombing in Lebanon earlier this month as "illegal aggression and indiscriminate bombing campaign", the United Nations Human Rights Council said.

"This is not self-defence. It is a blatant violation of the UN Charter, a deliberate destruction of prospects for peace, and an affront to multilateralism and the UN-based international order," the experts were quoted as saying in a statement.

SINGAPORE, April 15 (Reuters) - The U.S.-sanctioned tanker Rich Starry made its way back to the Strait of Hormuz on Wednesday after exiting the Gulf the day before, shipping data showed, failing to break through a U.S. blockade on vessels calling at Iranian ports.

U.S. President Donald Trump announced the blockade on Sunday after weekend peace talks in Islamabad between the U.S. and Iran failed to reach a deal.
