This move would seem to indicate that for now the Taliban are not interested in peace talks but continuation of armed struggle against NATO forces in Afghanistan. Baradar was arrested in Pakistan after US intelligence tipped Pakistani's off about his whereabouts. Pakistan's hand was more or less forced but Pakistan has not allowed Baradar out of their custody or even to be interviewed by the Americans yet. This is from the BBC.
Afghan Taliban name new deputy leaders after arrest
The Taliban say the new leaders are committed to the armed struggle
The Afghan Taliban say Mullah Omar has named two new deputies after the arrest of his military chief in Pakistan.
Abdul Qayuum Zakir and Mullah Akhtar Mohammad Mansoor succeed Mullah Abdul Ghani Baradar, who Pakistan is holding.
The aim was to send "a message that one arrest will not affect our movement", a senior Taliban leader said.
