DUBAI, April 16 (Reuters) - Saudi Arabia's two largest listed banks were the main drag on the index in early trade on Sunday on news that U.S. insurers have filed a lawsuit against the lenders over the Sept. 11, 2001, attacks, while National Bank of Kuwait rose on strong first quarter results.
Shares of Al Rajhi Bank were down 1.5 percent and, National Commercial Bank down 2.1 percent on news that the lawsuit was filed late on Wednesday in the U.S. District Court in Manhattan, by more than two dozen U.S. insurers affiliated with Travelers Cos, in the latest effort to hold entities in Saudi Arabia liable for the attacks.
The two banks, and companies affiliated with Osama bin Laden's family and several charities are being sued for at least $4.2 billion.
Riyadh's stock index was down 0.9 percent.
Elsewhere, shares of National Bank of Kuwait rose 1.5 percent after reporting an 8.1 percent rise in first quarter net profit to 85.4 million dinars ($280.78 million), slightly above two analysts' estimates of 83.3 million dinars and 84.0 million dinars.
The bank attributed the rise in net profit to higher net interest income and income from Islamic financing as a result of strong growth in business volumes.
The index on which it trades, however, was down 0.5 percent.
Dubai's index extended Thursday's 0.9 percent decline and fell 0.3 percent as 15 shares retreated and only 7 rose. Builder Arabtec, the most traded share, fell 1.6 percent.
