DUBAI (AFP) - A number of US diplomatic missions that closed on August 4 over an Al-Qaeda security alert reopened on Sunday, while others stayed shut for the Muslim holidays following the Ramadan holy month.

The embassy in the United Arab Emirates capital, Abu Dhabi, and the US consulate in Dubai reopened, as the holiday marking the end of the fasting month came to a close in the southern Gulf state.

The embassy in Libya also reopened on Sunday.

In Saudi Arabia, the Riyadh embassy and the consulates in Jeddah and Dhahran remained closed, as did the US Embassy in neighbouring Qatar. They are due to reopen on August 14, when the holidays end in those two nations.

In Bahrain and Kuwait, the American embassies are due to reopen on Monday.

Washington closed 19 of its missions in the Middle East and Africa last week following a security alert.

Communications intercepts reportedly included an attack order from Al-Qaeda leader Ayman al-Zawahiri to Yemen-based Al-Qaeda in the Arabian Peninsula.

The US said on Friday that all of the embassies it shut would reopen this week, except the mission in Yemen.
