Pakistani militants said they have sent hundreds of men to fight against Syrian President Bashar al - Assad along with various foreign - backed anti - government terrorists.

The move is aimed at bolstering ties with al - Qaeda’s central leadership.

More than two years since the start of the anti - Assad rebellion, Syria has become a magnet for foreign fighters who have flocked to the Middle Eastern nation.

Operating alongside militant groups such as the al Nusra Front, described by the United States as a branch of al - Qaida, they mainly come from nearby countries such as Libya and Tunisia.

On Sunday, Taliban commanders in Pakistan said they had also decided to join the cause, saying hundreds of fighters had gone to Syria to fight alongside their " Mujahedeen friends. "

" When our brothers needed our help, we sent hundreds of fighters along with our Arab friends, " one senior commander said.

Tensions erupted again on Thursday when an al - Qaida linked militant group assassinated one of Free Syrian Army ' s top commanders after a dispute in the port city of Latakia.

It also comes at a time when Assad ' s forces have been making gains on the Syrian battlefield.

Another Taliban commander in Pakistan, who also spoke on condition of anonymity, said the decision to send fighters to Syria came at the request of " Arab friends " but he refused to name countries which provoked Pakistani Taliban to head to Syria.

" Since our Arab brothers have come here for our support, we are bound to help them in their respective countries and that is what we did in Syria, " he told reporters.

" We have established our own camps in Syria. Some of our people go and then return after spending some time fighting there, " he added.

Taliban’s base in Syria have already been set up by Tehrik - i - Taliban Pakistan(TTP) helped by former Afghan fighters of Middle Eastern origin who sneaked into Syria in recent years.

Some 12 warfare and information technology experts had travelled to Syria during the past two months to assess the situation in the Arab country, Mohammad Amin, a Taliban operative and " coordinator of the Syrian base. ”

The base, according to the commander, which was set up six months ago sends " information and feedback " on the crisis.

The conflict in Syria started in March 2011, when peaceful pro - reform protests turned into a massive insurgency following the intervention of Western and regional states.

The unrest, which took in terrorist groups from across Europe, the Middle East and North Africa, has transpired as one of the bloodiest conflicts in recent history.
