May 10 (Reuters) - Most Gulf bourses ended lower on Sunday as fresh drone attacks and uncertainty over Iran peace talks weighed on investor sentiment, overshadowing relief over the first Qatari LNG tanker crossing the Strait of Hormuz since the war began.

The crossing came after nearly 48 hours of relative calm, though Kuwait reported hostile drones in its airspace and the UAE cited fresh attacks from Iran after weeks of relative quiet under a U.S.-announced ceasefire.

In Qatar, the index .QSI dropped 0.5%, with the Gulf's biggest lender Qatar National Bank QNBK.QA losing 1.5%.

Kuwait's shares .BKP retreated 0.5% and Bahrain .BAX was down 0.4%.

However, Saudi Arabia's benchmark index .TASI gained 0.8%, with Al Rajhi Bank 1120.SE rising 1.7%.

Oil major Saudi Aramco 2222.SE rose 0.8%, after reporting a 25% rise in first-quarter profit, as its East-West pipeline ran at full capacity to offset disruptions from U.S.-Iran tensions in the Strait of Hormuz.

Outside the Gulf, Egypt's blue-chip index .EGX30 advanced 1.9%, as most of its constituents were in positive territory including Commercial International Bank COMI.CA, which was up 1.3%.

Egypt will receive an additional $300 million from the World Bank to help address fallout from the Iran war, the lender's Egypt, Yemen and Djibouti director, Stephane Guimbert, said on Saturday.

Saudi Arabia	.TASI rose 0.8% to 11,115
Qatar	.QSI fell 0.5% to 10,664
Egypt	.EGX30 advanced 1.9% to 54,629
