As Tina noted in this comment, the protests at the airport have been called off. The airports are scheduled to open on Thursday. Apparently the news that the Prime Minister would step down, as would his government was enough for the protesters to call off their week long occupation of the airport.
I'd heard chatter that it would take at least a week for the airports to open, however, with cargo flights having resumed today it appears that they might pull off the Thursday call.
I'll have a better rundown of developments a little later.
