Hollywood star Angelina Jolie pledged yesterday to “do what she can” for flood-ravaged Pakistan.

The Oscar-winning actress, 35, was asked what she would do in her role as goodwill ambassador for the UN High Commissioner for Refugees (UNHCR) as she promoted her new action thriller, Salt, in London’s West End.

“I’m doing what I can. I’m talking to Ambassador [Richard] Holbrooke, the UN and people on the ground about how we can spend our money,” she said at the film’s premiere in Leicester Square.

Ms Jolie, who arrived without long-term partner Brad Pitt, added: “It’s unravelling every minute, it seems to be getting worse so we’re trying to keep track of it.”

The Changeling star is considering all her options and listening to advisers.

“A lot of people say it is important to visit but maybe in a month or two when the cameras go away – we don’t know when is the best time.

“We’re just going to keep on it and listen and take advice from the people on the ground as to what is best to do.”

Shimmering in a silver sequinned floor-length gown by Amanda Wakeley and Salvatore Ferragamo heels, Jolie thanked the thousands of fans who had waited for her – some camped out for 27 hours.

In Salt, which also stars Liev Schreiber and Chiwetel Ejiofor, she plays a CIA officer who goes on the run after being accused of being a Russian spy. “I love doing action and I think that when you like what you do, it’s contagious and hopefully people will like it too,” she said.

“I love it – I love to punch things, jump off things and shoot, so I’m lucky I got the job.” Salt opens in cinemas on Friday.
