KABUL, June 11 (Xinhuanet) -- The bodies of 11 Chinese construction workers, who were slain by gunmen in a terrorist attack in northern Afghanistan Thursday, arrived in the Afghan capital Friday.

    The four wounded Chinese workers are also on their way to Kabul,where they will receive medical treatment in a German hospital.

    So far, it remains unclear who were behind the deadly attack in Kunduz province.

    Meanwhile, Afghan Army Gen. Mohammad Daud told Chinese Ambassador to Afghanistan Sun Yuxi Friday that two suspects involved in the attack have been arrested.

    The general also promised that other suspects will be arrested soon, according to the Chinese Embassy.

    But the embassy did not give any words on the identities of the two suspects.

    The attack took place at around 01:00 a.m. local time (2030 GMT Wednesday) on a construction site 36 km south of Kunduz when some 20 gunmen opened fire at Chinese workers and security guards.

    This is the first major casualties China has encountered in Afghanistan in the past two years and also one of the worst terrorist attacks on foreigners since the former Taliban regime was ousted late in 2001.

    China, Afghanistan and the United Nations have condemned the terrorist attack.

    Chinese President Hu Jintao, who was in Poland for a state visit on Thursday, strongly condemned the terror attack against Chinese workers and urged the Afghan government and the UN mission in the country to investigate the incident, bring the terrorists to justice, and ensure safety and security of other Chinese citizens in Afghanistan.

    The Afghan government condemned the brutal killing, describing it as a cowardly act of terrorism.

    Acting Afghan President Mohammed Qasim Fahim, who assumed the role while President Hamid Karzai was visiting the United States, said Thursday he was "deeply distressed" by the killing of Chinese workers and strongly condemned "this cruel act of terror."Enditem¡¡
