Islamabad has so far refused to take part in a US probe into air strikes that killed 24 Pakistani soldiers, exacerbating fears Saturday of a prolonged US-Pakistani crisis as a result of the attack. Pakistan was invited to cooperate in the probe into the November 26 strikes on the Afghan border, which enraged Islamabad and propelled US-Pakistani ties to their rockiest in years, but officials have declined to do so.
"They have elected to date not to participate, but we would welcome their participation," said Pentagon press secretary George Little.
