Top officials from six Gulf Arab nations are gathering for talks expected to focus on regional security in the tiny island kingdom of Bahrain.

Joining the two-day summit of the Gulf Cooperation Council beginning Wednesday is British Prime Minister Theresa May, the first female leader to participate in the annual talks.

May addressed British sailors aboard the amphibious assault ship HMS Ocean earlier in the day, highlighting her country's commitment to the Persian Gulf region. The UK is building a new naval base in Bahrain.

That decision has drawn criticism from human rights advocates, who point to the jailing of several activists and opposition figures in recent years.

Amnesty International has urged May to raise concerns about human rights violations throughout the Gulf during her meeting.
