Multinational forces’ strikes against Tripoli entered their fourth day on Wednesday.

Foreign media journalists said two explosions were heard at around 3:40 a.m. Wednesday and that they saw about ten minutes of flashing lights from antiaircraft shooting.

According to AFP, a loud explosion was heard in Tripoli and that forces of Libyan leader Muammar Gadhafi fired back toward multinational coalition’s attacks with antiaircraft firearms.

According to foreign media, Gadhafi’s forces are shifting their attack target to western regions from eastern areas as multinational forces are actively taking part in battles in the eastern regions and as Benghazi is the stronghold of rebel forces.

The media said that Gadhafi’s men are attacking the western cities of Mizrata and Zintan after failing to win back Benghazi.
