Madonna has withdrawn a promotional video for her latest single, saying it is "inappropriate" at a time of war.

It had been due to be shown on TV channels later this week, but Madonna has now dropped it "out of respect for the armed forces".
I do not want to risk offending
anyone who might misinterpret the meaning of this video
She said: "It was filmed before the war started and I do not believe it is
appropriate to air it at this time."
The 44-year-old singer added: "Due to the volatile state of the world and out of sensitivity and respect to
the armed forces, who I support and pray for, I do not want to risk offending
anyone who might misinterpret the meaning of this video."
After some commentators criticised the video, Madonna released a statement denying she was "anti-Bush" and insisting she was "pro-peace".
She is not the first singer to have become embroiled in controversy over the conflict in Iraq.
Robbie Williams and Lenny Kravitz have recorded anti-war songs, while Ronan Keating and Coldplay's Chris Martin have made outspoken protests.
Among the highest profile critics is George Michael, who has recorded Don McLean's protest song The Grave for a War Child charity album in aid of Iraqi children.

The video for Michael's last single, Shoot the Dog, showed Tony Blair as a poodle on the White House lawn.
He also performed an anti-war version of his hit Faith with Ms Dynamite at the Brit Awards.
Other stars backing the War Child project include Sir Paul McCartney, David Bowie and Yusuf Islam - formerly Cat Stevens.
At this year's Grammys in New York, singers Sheryl Crow, Bonnie Raitt and Fred Durst made their own low-key protests.
Madonna's single is due for release on 14 April, with a new album out the following week.
She recently criticised the trend for manufactured pop acts and the stream of TV talent searches.
Last week she swept the Razzies for the worst film of the year, with Swept Away which was directed by her husband, Guy Ritchie.
