WASHINGTON, June 5 (Reuters) - U.S. President ‌Donald Trump's special envoy Steve Witkoff and son-in-law ​Jared Kushner traveled to the Oak Ridge National Laboratory in Tennessee on Thursday to consult with experts that could play a role in nuclear negotiations with Iran, a source familiar with the trip said on Friday.

Israeli settlers have recently set fire to crops in the area, and Jazi fears his wheat could suffer a similar fate.

Their village of As-Sawiyah, in the centre of the occupied West Bank, sits in a valley dominated by hills on top of which three settlements stand.

"The settlers have set fires twice already -- yesterday and the day before," Jazi told AFP.

BEIRUT, June 5 (Reuters) - Lebanese President Joseph Aoun accused Iran of using Lebanon as a bargaining chip in its negotiations with the United States on Friday, in some of his toughest criticism yet of Tehran and its Lebanese ally Hezbollah as it wages war with Israel.

In a CNN interview, Aoun said "the people of Lebanon are paying the price ... for the sake" of Iran's interests, and were "fed up" with war between Israel and Hezbollah - comments reflecting deep divisions along Lebanon's confessional and political faultlines.

VIENNA/PARIS, June 5 (Reuters) - The United States is preparing a draft resolution condemning Iran ahead of next week's meeting of the U.N. nuclear watchdog's Board of Governors, diplomats said on Friday, a step that could complicate wider talks between the U.S. and Iran.

Iran says it never would.

LONDON, June 5 (Reuters) - Here are the main issues between the United States and Iran as they seek a deal to end their war, which is now in its fourth month:

HORMUZ AND GULF BLOCKADE

Iran's closure of the Strait of Hormuz, normally the conduit for around a fifth of global oil and liquefied natural gas shipments, has caused an unprecedented oil supply shock, driving up fuel, food and fertiliser prices.

Reopening the strait is Washington's top priority and Tehran's main point of leverage, but it could take time.
