BEIRUT (AP) — A military buildup is taking place along Turkey's border with Syria.
Turkey has deployed anti-aircraft guns, rocket launchers and other weapons. Turkey is a former ally of Syria, but it's become one of the strongest critics of Bashar Assad. And tensions have escalated after Syria's downing of a Turkish military plane last week.
Meanwhile, a bomb exploded in central Damascus near a busy market and the country's main justice complex. At least three people were wounded, and cars were damaged in a parking lot. It's not clear who was behind the bombing.
Much of the violence that has gripped Syria since the uprising against Assad began last year has been sanctioned by the government to crush dissent. But rebel fighters are launching increasingly deadly attacks on regime targets. And several massive suicide attacks this year suggest al-Qaida or other extremists are joining the fray.
World powers will meet Saturday in Geneva for talks on Syria, but few observers expect a major breakthrough.
