Gunmen possibly on inaccessible 3rd floor, accessing thru the stairs a suicide mission coz:

a. Vantage position of the gunmen {higher ground}
b. Snipers with surprising accuracy (no missing)
c. Machine guns
d. Explosives
e. Human shields n the need to save as many lives as possible.
f. Very intelligent/well trained enemy.
g. Enemy on suicide mission
h. Only 2 entry points-easy to cover with maximum firepower

These factors combined would be a tough nut to crack even for the best trained n equipped force in the world. Its a freaking dilemma. Be patient guys, fatigue is setting in. Jack Bauers of this world would fail miserably. Several of the gunmen are dead though, and more will die, its just a matter of planning n time.

First pictures of the terrorists:

ooook.... so, who was trying to "rescue" the shoes? the hostages or the terrorists?

Once a king called upon all of his wise men and asked them, “Is there a mantra which works in every situation, in every circumstance, in every place and in every time – in every joy, every sorrow, every defeat, and every victory – one answer for all questions? Something which can help me when none of you is able to advise me? Tell me, is there any mantra?”
All the wise men were puzzled by the King’s question. After a lengthy discussion, an old man suggested something which appealed to all of them. They went to the King and gave him a ring with words engraved into it, with a condition that the King was not to read it out of curiosity. Only if, in extreme danger, when the King finds himself alone and there seems to be no way out, only then he can read it. The King wore the ring without reading the engraving.
Some time later, the neighbors attacked the kingdom. The King and his army fought bravely but lost the battle. The King fled on his horse and the enemies followed him. The King found himself standing at the mouth of a deep ditch. If he jumped into it, there would be no way out. The sound of the enemy horses were approaching fast and the King became restless. There was nowhere else to go.
The King remembered his ring and about the engraving. He decided to read the message.
“This, too, shall pass.”
The King read it again and again until something struck him. Yes! This, too, will pass. Only a few days ago, I was enjoying my kingdom; I was the mightiest of all the Kings. Yet today, the Kingdom and all its pleasures are gone. I am trying to flee from my enemies. But just as those days of luxuries have gone, this time of danger will pass, too. Calm came over the King. He remained still and silent. The King looked around at the place where he was standing and realized how beautiful it was. He had never known that such a beautiful place existed in his Kingdom.
The revelation of the ring’s message had a great effect on him. He relaxed and forgot about his pursuing enemies. After a while, he realized that the noise of galloping horses had receded and that his enemies had lost him.
The King gathered himself and reorganized his shambled forces and fought again. He defeated the enemy and reclaimed his empire. When he returned to the city after the victory, he was received with much fanfare. The whole capital was rejoicing and everyone was in a festive mood. Flowers rained down upon the King from every house, from every terrace as he trotted by. People were dancing and singing. In this moment the King thought to himself, “I am one of the bravest and greatest Kings. It is not easy to defeat me.” In all of the celebration an ego emerged in the King.
Then a ray of sunlight caught the King’s ring and sharply flashed into his eye reminding him of its message, “This, too, shall pass.”
He lowered his gaze and his valiant expression changed to one of humility. He realized, again, that if this, too, is going to pass, it is not yours. The defeat was not yours. The victory was not yours. You are just a player. Everything passes by. We are witnesses of all of this. We are the beholders.
Happiness comes and goes. Sorrow comes and goes. And Life?
This, too, shall pass.
