Armed Hashid tribesmen clashed with Republican Guards under the command of Ahmed Saleh, the president's son, in central Sana'a. Fighting lasted about half an hour. The city was divided during the day by fighters on both sides blocking streets and erecting makeshift checkpoints, Al Jazeera English reported. Sana'a International Airport was reportedly closed due to a threat by tribesmen to attack arriving and departing planes.
