VIDEO - Air Force experiences moments of tension and anxiety: Hizbullah's television station and other media in the Arab world reported that an Israel Air Force aircraft crashed in eastern Beirut, in an area called al-Warwar. The al-Jazeera network aired a short film showing the "crash" – a ball of fire quickly falling into buildings, leaving behind trail of smoke. IDF officials said following a short inquiry that all aircrafts were safe. Military officials raised the possibility that it was a box carrying leaflets which failed to open and fell down, a Hizbullah missile or "another internal incident." On Friday, Hizbullah managed to hit a Navy missile boat off the shores of Beirut. After the incident, Hassan Nasrallah announced that his people were preparing "additional surprises" for the IDF. Simultaneously, the Air Force reportedly resumed its attacks on Hizbullah strongholds in south Beirut on Monday afternoon. According to one of the reports, a target near the president's palace was also attacked. Reports in the foreign media pointed to a ground and firm entry into the ruined Hizbullah posts north of the border. IDF officials denied the reports.
