MIDEAST STOCKS-Major Gulf markets mixed as investors await clarity on US-Iran talks

April 6 (Reuters) - Major Gulf markets were mixed in early trade on Monday as investors awaited clarity on reports of U.S.-Iran ceasefire talks that came after U.S. President Donald Trump warned Tehran of "hell" unless the Strait of Hormuz was reopened.

Trump warned in an expletive-laden Easter Sunday social media post that he would order strikes on Iran's power plants and bridges on Tuesday if the strategic waterway was not reopened.

Iran and the United States have received a proposal to end hostilities that could take effect on Monday and lead to the reopening of the Strait of Hormuz, a source familiar with the matter.

Saudi Arabia's benchmark index .TASI eased 0.2%, with Al Rajhi Bank 1120.SE losing 0.3%.

Dubai's main share index .DFMGI fell 0.2%, hit by a 2.5% slide in Emaar Properties EMAR.DU.

In Abu Dhabi, the index .FTFADGI gained 0.4%.

UAE official Anwar Gargash said any settlement of the U.S.-Iran war must guarantee passage through the Strait of Hormuz. Gargash warned that any deal that does not restrain Iran's nuclear programme and its missile and drone arsenal would pave the way for "a more dangerous, more volatile Middle East."

The UAE was hit harder than any other Gulf state, according to regional officials, following Tehran's retaliation for U.S.-Israeli strikes with missiles and drones that targeted Israeli and U.S. bases and key Gulf infrastructure in the region.

The Qatari benchmark .QSI advanced 1%, buoyed by a 0.6% rise in the Gulf's biggest lender Qatar National Bank QNBK.QA.
