[BBC defense correspondent Andrew] Gilligan casts doubt on source of hotel attack
He added that after examining the scene he concluded it was virtually impossible for the US tank to have fired on the 15th floor room."I have to say I rather doubt it and, having been underneath it and looking up now just before it got dark at the hole again in the side of the hotel, I still doubt it.
"For a start the damage to the hotel is superficial, it's only the masonry that's been torn off in a very small area, a tank shell would have done more damage I feel.
"Secondly the angle that the tank would have to have reached to hit that roof, it would more or less have had to have shot just round the corner and I don't think even the Americans have got those kinds of weapons."
Gilligan said although American tank fire hit other parts of the hotel, it was possible an Iraqi attack was responsible for the journalists' deaths.
"Now the Americans have admitted they fired at the hotel. There was damage to other parts of the hotel.
"This was the main one the 15th floor room, where the two people were killed and three injured, but there was also damage to rooms on the 14th and 17th floors.
"Now that might have been the responsibility of the Americans.
"This might have been the responsibility of someone else, maybe some Saddam Fedayeen with a rocket-propelled grenade, who did not like the fact the Reuters guy was shooting footage from his balcony at the time of the attack.
"That is pure speculation. I just think there must still be some doubt over this area."
