Well the Israeli's managed to seiza a ship with a haul of 500 tonnes of weapons and missiles on its way to Hezbollah via a most circuitous route, the Israelis claimed that the weapons had been loaded on board the Antiguan flagged ship at Egypt and were on their way to Syria via Cyprus and Lebanon.
You can check out a good version of events here http://www.timesonline.co.uk/tol/news/world/middle_east/article6903092.ece
The fact is that this weapons seizure is significant only in terms of the fact that it doesn't happen often that a haul of this size is grabbed by the Israelis, it will not harm Hezbollah in any meaningful way. Israeli intelligence claims that they have more than replenished their supplies since the Lebanon War in 2006.
Really this is just another in a long list of incidents which have been raising the heat on the Israeli Lebanese border for several months now, there was this incident:
http://www.haaretz.com/hasen/spages/1120512.html when a senior Hezbollah militant was killed in an explosion in the garage of a building close to the border. Reports on that have been highly speculative and it is unlikely that we will ever really know what happened there save that this senior Hezbollah guy is dead.
There have been occasional trades of fire between the two groups the most recent being September 11 2009
this is reminiscent of the raise in tempo along the border before Hezbollah decided to kidnap a couple of Israeli soldiers in a highly professional cross border raid which led to Ehud Olmert's lashing out attack that brought the whole of Lebanon to a standstill.
So it looks like there is going to be a round two with hezbollah at somepoint in the future, probably not too soon as the tempo of attacks isn't particularly high, but it is getting higher and the showdown is getting closer...
