"Peace will be achieved only through direct negotiations and not through unilateral moves," Netanyahu told Guido Westerwelle, according to a statement issued by his office after the two met in Jerusalem on Monday.

Turkish Prime Minister Recep Tayyip Erdogan warned in comments published Tuesday that Syria could plunge into "civil war," as he began a tour of Arab countries where uprisings ousted autocratic leaders.

Al-Qaida in the Arabian Peninsula (AQAP) has claimed a suicide bombing in mid-August against a gathering of Shiite Huthi rebels in northern Yemen, monitoring group SITE Intelligence said on Tuesday.

The chief of Libya's revolutionary movement told thousands of cheering Libyans in Tripoli Monday to strive for a civil, democratic state, while loyalists of the hunted dictator Moammar Gadhafi killed at least 15 opposition fighters in an attack on a key oil town in Libya's east.

Gunmen killed 22 Shiite Muslim pilgrims on their way to Syria as they were passing through a predominantly Sunni Iraqi province from the shrine city of Karbala, officials said on Tuesday.
