A spokesman for the Pakistani Taliban said that the team of militants they sent into Karachi's PNS Mehran naval base on Sunday night had enough supplies to survive a three-day siege.
"They have enough ammunition and food and they can fight and survive for three days," Taliban spokesman Ehsanullah Ehsan said.
He said that up to 22 militants were assigned to launch the attack. Accounts are unclear, but up to five militants may have been killed by Pakistani troops. The remaining are holed up in a building on the base exchanging fire with commandos.
