Your comment almost reads as satire it's so ridiculous. If there is any chance of civilians in the building:

Establish surveillance around the building. Israel has surveillance companies that work as contractors for other nation's military, including the USA. Surround the building, entrench soldiers, send in some sort of communication equipment (even just throwing in a walkie talkie), negotiate food and water as needed but generally starve them out. As a last resort, move troops through the building.

If there is no chance of civilians in the building:

Establish surveillance around the building. If no structural damage exists: move troops through the building.

What Israel does:

Bomb everything within 40m. Leave nothing intact.
