A relative of a Pakistani Taliban leader just released from custody, has vowed to continue armed struggle for Islamic law in the country's northwest despite the signing of a peace accord.

Maulana Fazlullah, son-in-law of Sufi Muhammad, said on Tuesday that his group will not lay down their arms until the government enforces the Shariah.

Pakistan released Muhammad on Monday after a deal reached with the government of North West Frontier Province (NWFP).

The deal, in which the group renounced violence in return for being allowed to peacefully campaign for the Shariah, appears to be part of the new government's efforts to engage in dialogue with armed groups fighting against the state.

Battle to continue

But Muslim Khan, a spokesman for Fazlullah, said that fighters allied with Fazlullah will not cease battle.

"We welcome the release of Sufi Muhammad, but we will only lay down arms when the government would enforce Sharia', Khan said.

"We are fighting for the enforcement of Islam. If the government enforces Sharia today, we will stop our struggle.

"But we want to see practical steps from the government, and not just the promises."

Khan said that the fighters he spoke for have not seen the text of the accord signed by Muhammad.

Last year supporters of Fazlullah fought with security forces for control of the northwest's Swat Valley.

Major-General Athar Abbas, Pakistan's army spokesman, said that no decision had been made to withdraw the army from Swat Valley.

Differences

Sufi Muhammad, believed to be in his 70s, sent thousands to battle the US-led invasion of Afghanistan in 2001.

He has spent the past five months in a hospital in Peshawar due to ill health.

Muhammad was sentenced to three years for the illegal possession of a weapon but he remained in government custody until he was released and the accord was signed.

His group, Tehrik Nifaz-e-Sharia Mohammed (Movement for the Enforcement of Islamic Law), resurfaced under Fazlullah's leadership after his arrest in 2002.

Fazlullah's group, who is reportedly at odds with Muhammad, wants a Taliban-like system.
