US refuses to return to frontline in Libya

BERLIN (AFP) – The United States resisted pressure Thursday to return its warplanes to the frontline in Libya even as NATO vowed to keep bombing Moamer Kadhafi's forces and pressed the strongman to quit.
As NATO foreign ministers meeting in Berlin struggled to heal a rift over the mission, rebels said Kadhafi forces shelled the city of Misrata, killing 13 people, while blasts rocked Tripoli as jets screamed over the capital.
The ministers issued a joint statement calling on Kadhafi to leave power, and they vowed to maintain "a high operational tempo" against regime targets and "exert this pressure as long as necessary."
Despite the show of unity, the allies remained divided over French and British calls to contribute more jets to the mission. Nearly a month of coalition strikes have failed to shift the balance of power so far.
French Foreign Minister Alain Juppe made a personal appeal to US Secretary of State Hillary Clinton for Washington to resume major air raids in Libya, but he said his plea was rebuffed.
