Afghanistan launched a cross-border attack on Pakistan late Thursday, saying it was in retaliation for deadly Pakistani airstrikes on Afghan border areas Sunday. Pakistan then carried out airstrikes in Kabul and two other Afghan provinces early Friday, saying it targeted military installations.

"We have targeted important military targets in Pakistan, sending a message that our hands can reach their throats and that we will respond to every evil act of Pakistan," Afghan government spokesman Zabiullah Mujahid said in televised comments from Kandahar Friday. "Pakistan has never sought to resolve problems through dialogue."
