Libyan talks amid stalemate in fighting

International delegates are to hold talks on the conflict in Libya, amid calls for Nato to intensify its campaign there.

At the talks in Qatar, delegates from the "contact group" on Libya will hear from leaders of the rebels seeking to topple Libyan ruler Muammar Gaddafi.

The talks come amid a worsening humanitarian crisis in the rebel-held city of Misrata, where pro-Gaddafi forces have continued to launched fresh attacks.
