Tunisia has arrested a second Moroccan suspect over a deadly attack in March on the Bardo museum in Tunis, detaining him at the border with Libya, the interior ministry said Thursday.

Noureddine al-Naibi was arrested on Sunday at the Ras Jedir border post on suspicion of indirect involvement in the attack, ministry spokesman Mohamed Ali Aroui told AFP.

Republican presidential candidate Rand Paul is blaming his own party for the rise of the Islamic State group.

The senator from Kentucky said Wednesday that the Republicans' foreign policy hawks "created these people." That assertion led potential 2016 rival Bobby Jindal, Louisiana's governor, to say Paul was unqualified to be president.

A four-day meeting of Libyan tribal leaders opened Monday in Egypt which is exploring ways to unite warring parties and bring peace to its oil-rich neighbor.

Those attending the conference at a Cairo hotel were members of tribes that back the internationally recognized government based in the eastern Libyan city of Tobruk.

Forces loyal to Libya's internationally recognized government carried out an air strike Sunday on an oil tanker delivering its cargo to a power plant run by the rival administration, a report said.

The General Electricity Company denounced as "sabotage" the attack at the plant near Sirte, in central Libya, saying it was likely to cause disruptions to power supplies across the country due to a lack of fuel.

The bodies of five Tunisian migrants trying to reach the Italian island of Lampedusa were recovered from the sea Saturday while 49 others were rescued, Tunisia's coast guard said.

The coast guard station in Teboulba said the five migrants who had drowned were recovered and the others rescued in the night off the town's coast.

Despite cries of alarm from European politicians over the deaths of migrants in the Mediterranean, African leaders have been silent over an issue they fear underlines their weak governance, say campaigners.

For years Libya has been a stepping stone for Africans seeking to get to Europe, fleeing conflict, economic hardship and instability often in rickety, unseaworthy vessels.

Dozens of Tunisians who had been detained in Libya by a militia were set free in the capital Tripoli on Thursday, officials said.

Mohamed Abdelsalam al-Kuwiri, who heads a unit in the Tripoli-based government that combats illegal migration, said his officers helped secure the release of 42 Tunisians.

One day after a deadly 2012 attack on a U.S. mission in Libya, then secretary of state Hillary Clinton was told confidentially al-Qaida-linked militants were likely behind the assault, a U.S. daily said Thursday, publishing some of her emails.

Yet it took several days for the White House to admit it was probing whether al-Qaida had any links to the storming of the mission in Benghazi in which U.S. Ambassador Chris Stevens and three other Americans were killed.

Ten soldiers and a militiaman were killed in fresh violence in conflict-strewn Libya, security and medical sources said Thursday.

They said 10 soldiers were killed and 36 wounded in clashes Wednesday in the eastern city of Benghazi, birthplace of the 2011 revolt that ousted longtime strongman Moammar Gadhafi.

Libya's internationally recognized government rejected Monday any military operation against ships carrying illegal migrants after EU nations approved plans for a naval mission starting next month to fight human traffickers.

"Any military action must be done with the cooperation of the Libyan authorities," government spokesman Hatem el-Ouraybi told AFP by telephone.
