More accusations and counter-accusations over the deaths of two soldiers in Sa'dah. Could this be the beginning of the sixth war? Here at Waq al-waq, we have been warning for a week or so that all the planets are lining up for another round of fighting. The last round needed a motorcycle bomb outside a mosque, but previous rounds have needed less to light the fuse.

We are all hoping, of course, that both sides can step back from the brink but it does not look good.
