Iran's foreign minister on Sunday called on Gulf Arab neighbors to cooperate against the common threat of "terrorism, extremism and sectarianism," but insisted that Tehran's policy will not change.

"Our message to the countries of the region is that we should cooperate to face the common threat," Mohammad Javad Zarif told reporters after meeting Kuwaiti officials in his first foreign trip following the nuclear deal with world powers.

Iran's top diplomat Mohammad Javad Zarif will visit Kuwait, Qatar and Iraq this weekend, the ISNA press agency said Friday, following a landmark nuclear deal between Tehran and world powers.

A new Kuwaiti law imposing mandatory DNA tests on citizens and foreigners violates the right to personal privacy and should be amended, Human Rights Watch said Tuesday.

Kuwait's public prosecution has demanded the death penalty for 11 of 29 suspects charged over the suicide bombing of a Shiite mosque last month, a newspaper reported Wednesday.

Kuwait's financial reserves defied a slump in oil prices to hit a record 179.2 billion dinars ($592 billion) at the end of the 2014-15 financial year, a report said Thursday.

Two brothers arrested in Saudi Arabia had transported the explosives used in the suicide bombing of a Shiite mosque in Kuwait, the interior ministry said Tuesday.
