Libyan pro-government forces on Wednesday seized control of Bani Walid, one of the last bastions of Moammar Gadhafi's ousted regime, an AFP correspondent in the town said.

Tensions soared around Gaza on Wednesday after Israeli air raids killed four fighters and Palestinian armed groups fired 68 rockets at southern Israel, seriously wounding two people.

Libya on Tuesday celebrated the first anniversary of its "liberation" from the regime of Moammar Gadhafi, even as fighting flared in a former bastion of the slain dictator.
