KABUL, Dec 4 (Reuters) - Afghan President Hamid Karzai will not allow any minister to sign a security pact with the United States unless key demands are met, the president's spokesman said on Wednesday.

The statement came the day after U.S Secretary of State John Kerry said the bilateral security agreement (BSA) could be signed by Karzai's defence minister, Bismillah Khan Mohammadi.

Karazi is demanding the United States encourage a nascent peace process with the Taliban and immediately end U.S raids on Afghan homes, Karzai's spokesman Aimal Faizi told Reuters.

"As long as these demands are not accepted, President Karzai will not authorise any minister to sign it," Faizi said. (Reporting by Hamid Shalizi; Writing by Dylan Welch; Editing by Mark Trevelyan)
