All days d-4

The chief of the Pakistani Taleban, Baitullah Mehsud, has told the BBC his group was behind Monday's deadly attack on a police academy in Lahore.
He said the attack was "in retaliation for the continued drone strikes by the US in collaboration with Pakistan on our people".
He also claimed responsibility for two other recent deadly attacks.
Baitullah Mehsud said the attacks would continue "until the Pakistan government stops supporting the Americans".
Security officials are interrogating at least four suspects captured after the attack, police say.
