The navy Sunday said a boat suspected of carrying explosives was speeding toward a Yemeni warship off the coast of volatile Abyan province late Saturday. A Yemeni commander said navy ships fired on the boat and sank it after it ignored several warning shots.
No one has claimed responsibility for the attack, but al-Qaida has used boats in the past to attack warships.
In October 2000, an al-Qaida attack on the USS Cole Navy destroyer in the port of Aden killed 17 American sailors.
Yemeni security forces continue to battle al-Qaida insurgents in Abyan province, where the militants have captured areas including the provincial capital, Zinjibar, and the town of Jaar.
SYRIA has rejected an Arab League statement calling for an end to deadly violence that has shaken the country, as the government cracks down on a five-month-old pro-democracy uprising.
In a statement issued early Sunday after an emergency meeting in Cairo, the Arab bloc called for a stop to “bloodshed” in Syria “before it is too late.” It also said Arab League Secretary-General Nabil Elaraby is ready to visit Syria to try to resolve the crisis, but did not say when the trip will happen.
Syria responded with a protest note accusing the Arab League of violating diplomatic protocol and saying Damascus regards the statement as “non-existent.”
IRAQ: Iraqi officials say a suicide bomber has blown himself up inside the largest Sunni mosque in Baghdad, killing at least 28 people and wounding 37 others during special prayers for the holy Muslim month of Ramadan.
Interior Ministry officials said the blast took place late Sunday inside the blue-domed Um al-Qura mosque in the Iraqi capital. They said Sunni lawmaker Khalid al-Fahdawi, a representative from western Anbar Province, is among the dead.
No group immediately claimed responsibly for the attack, which came just days before the end of Ramadan.
At least four more people died in other violence Sunday.
U.S. and Iraqi officials have expressed concern about Iraq's ability to handle security after U.S. forces withdraw at the end of the year.
In the northern city of Mosul, an explosive device attached to a police car killed a policeman and wounded four others, while in the ethnically mixed city of Baquba, militants killed three people in a car at a fake checkpoint.
In Baghdad, two additional bomb attacks wounded at least four people. And a fifth bomb attack wounded two people in the town of Tuz Khurmatu, some 175 kilometers north of Baghdad.
LIBYA: Survivors and rights groups say pro-Gadhafi forces committed possible war crimes as rebels moved into the Libyan capital last week, killing scores of detainees and arbitrarily executing dozens of civilians.
Human Rights Watch said Sunday that its researchers have documented more than 110 corpses in four locations in Tripoli, many of whom appear to have been killed execution style either while in detention or with their hands bound.
The group's Middle East and North Africa director said the execution of detainees days before they would have been freed is a “sickening low” in the Libyan government's behavior.
A metal warehouse in a compound controlled until last week by Libya's elite Khamis Brigade contains about 50 scorched skeletons. A VOA correspondent who visited the warehouse says outside, another eight bodies lie on the grass, one with his hands tied behind his back. A survivor told VOA that as rebel forces approached, loyalist soldiers shot their prisoners, then tried to burn the bodies.
So far, there have been no specific allegations of atrocities carried out by rebel fighters. But it remains unclear who is responsible for some of the killings, including those of dozens of dark-skinned men whose bodies were found in two areas of Tripoli.
The gruesome discoveries come as rebels say they have captured the coastal town of Bin Jawad after several days battling fighters loyal to Moammar Gadhafi. The anti-Gadhafi forces say they seized the town on Sunday. Bin Jawad is about 520 kilometers east of the capital, Tripoli.
Rebels say they are surrounding Mr. Gadhafi's hometown, Sirte, and are negotiating with tribal leaders there for a peaceful surrender. Sirte is considered one place where the former leader may have fled to go into hiding. He has dropped out of sight since rebel fighters seized Tripoli.
A Red Cross ship entered Tripoli harbor Sunday carrying supplies for the city, which saw days of fighting between rebels and Gadhafi supporters last week. A VOA correspondent in Tripoli says the city has widespread shortages of medicine, drinking water and other basic supplies. Many areas are still without electricity.
Libyan rebels have made clear they won't return the Libyan responsible for the murder of 270 people back to serve out the rest of his sentence.
The Transitional National Council's justice minister told reporters in Tripoli that Abdel Baset al-Megrahi already has been tried and convicted in Scotland for bombing Pan Am flight 103. He said the rebels will not hand over Libyan citizens as former leader Moammar Gadhafi did.
Later Sunday, CNN television reported that al-Megrahi had been found in Tripoli and appeared “near death.”
A correspondent for the network said he found al-Megrahi at a spacious villa in the Libyan capital guarded by at least six security cameras and attended to by relatives.
CNN footage showed al-Megrahi apparently laying unconscious in a bed. His family said he is being kept alive with oxygen and a fluid drip, that he has stopped eating and occasionally lapses into a coma.
Scottish authorities freed al-Megrahi in 2009 on compassionate grounds. Doctors said he had terminal cancer and only months to live. He had served eight years of a minimum 27-year prison sentence.
The decision to release al-Megrahi outraged the families of the Lockerbie bombing victims, many of whom were from the U.S. The fall of the Gadhafi government has sparked hopes that Libya's new leaders would be willing to extradite the convicted Lockerbie bomber.
IRAN: Iran's semi-official news agency says the country's top leader has pardoned 100 prisoners.
Mehr news agency reports that 70 of the prisoners issued pardons by Ayatollah Ali Khamenei were released immediately late Saturday.
Officials say some of the pardoned prisoners participated in the 2009 protests following the re-election of President Mahmoud Ahmadinejad.
Authorities have not released the names of the prisoners.
Iran traditionally releases prisoners on religious occasions, including the end of the Muslim holy month of Ramadan, which is in its final days.
