War Begins!

is episode 262 of the Naruto: Shippūden anime.

Summary
The remaining members of the Infiltration and Reconnaissance Party are pursued by Akatsuki's Surprise Attack and Diversion Platoon but are hampered by Muta Aburame's Insect Jamming Technique. Separated from his team-mates, Muta instructs his kikaichū to carry the intel they had on Akatsuki to the Allied Shinobi Forces headquarters. The Surprise Attack Division arrives in enemy airspace with Omoi feeling great apprehension about the war. The other members are assigned their duties and no sooner than all their preparation were readied are does Zaji — the group's sensor — notifies the team that his sensory abilities were being disrupted. After seeing an injured Muta, Zaji rushes to help him. It is revealed that Muta was being controlled by Sasori. As Deidara detonates the explosive clay they had stuffed into Muta's insect jar, through the quick actions of Kankurō, Zaji is saved from the explosion while Ittan saves the team with his Earth Release: Moving Earth Core technique. With barely any time to relent, the team is set upon again by two shinobi who turn out to be their comrades once again. After fending them off, Sai arrives in time to deflect a secondary attack by Shin — whom Sai is shocked to see. Omoi becomes enraged that Akatsuki would use such underhanded tactics as to have them fight their family and comrades and launches another attack on Deidara freeing Tokuma and Ranka. Using this opportunity Ittan raises the earth as Kankurō drags Sasori down using the severed chakra threads sending Deidara and Sasori crashing into one another. As the regenerate, Kankurō summons his Scorpion puppet and the divisions prepare for an all-out battle.
