Lebanese authorities have accused Syrian border guards of shooting at a Lebanese fishing boat that approached the Syrian coast during the night.
Tensions on the border have been growing – with Lebanon desperate to show it is patrolling its border well, as Israel accuses it of allowing Hizbollah weapons to come in. Meanwhile, Syria is worried that Islamist militants are crossing into Syria from Lebanon.
Last year, Lebanese soldiers shot dead a Syrian man near the border.
Syrian authorities have also held, and released, several Lebanese fishermen who entered Syrian waters.
One of the problems (on land, at least), is the lack of a clearly defined border.
