MOSCOW, July 8 (Reuters) - Russia introduced a ban on diesel exports on Wednesday as part of a raft of measures to support the domestic fuel market after systematic Ukrainian drone attacks on oil refineries triggered shortages and price spikes in some regions.

Drivers in many regions are facing hours-long lines to refuel, as intensifying Ukrainian strikes on Russian energy infrastructure squeeze supplies of diesel and gasoline.

July 8 (Reuters) - Donald Trump’s Board of Peace is planning a pilot humanitarian zone for Gazans as a way to kickstart the U.S. president's stalled peace plan, regardless of whether a deal is reached with Hamas on the peace plan's second phase, a board official said.

The official didn't specify the location, but said the Trump-appointed board had identified secure areas that could host tens of thousands of Gazans, where goods and services could be scaled up to meet the humanitarian needs of those willing to move there.

ANKARA, July 8 (Reuters) - U.S. President Donald Trump said on Wednesday that he thought Israel would withdraw troops from southern Lebanon because it wanted to take that step, despite comments from Israel's leader indicating otherwise.

Trump told reporters at the NATO Summit in Ankara that he had discussed a withdrawal with Israeli Prime Minister Benjamin Netanyahu.

"Yeah, I think they're going to. I think they want to," Trump said. "So we have a deal with Israel and Lebanon. Yeah, they'll leave. And I think it's going to work out very well."

ANKARA, July 8 (Reuters) - President Donald Trump told NATO allies he wanted to keep the United States in the alliance at a leaders' meeting in Ankara on Wednesday, a source familiar with the talks told Reuters.

Inside the closed summit meeting, he also said the U.S. was prepared to continue selling weapons to allies no matter how they were put to use, the source said, requesting anonymity.

The source quoted Trump as having told NATO leaders: "We want to remain with you".

LONDON, July 8 (Reuters) - A Qatari tanker loaded with liquefied natural gas (LNG) was at risk of exploding, one source said, after it sustained significant damage in an attack on the Omani side of the Strait of Hormuz on Tuesday.

While the LNG industry has experienced a few accidents at onshore facilities, there has never been a catastrophic LNG cargo-tank explosion on a commercial LNG carrier at sea. Recent targeting of energy shipping vessels by belligerents in both the Ukraine and Iran wars has raised concerns, however.

ANKARA, July 8 (Reuters) - U.S. President Donald Trump said on Wednesday that the memorandum of understanding signed with Iran to end the conflict was "over", adding he didn't want to engage with Tehran.

The interim ceasefire agreement signed between Washington and Tehran — under the mediation of Pakistan — was intended to provide a 60-day window for negotiations on a permanent agreement, but indirect talks in Qatar ended last week with no sign of headway and the U.S. military unleashed a new wave of strikes against Iran on Tuesday.
