青年党：激进分子仍在肯尼亚商厦扣押着人质

The Somali militant group al-Shabab says its fighters are still holding hostages inside the Kenyan mall where gunmen began a deadly siege on Saturday.

The group said in a series of Twitter messages Tuesday that militants were "holding their ground" at the Westgate shopping center in Nairobi, and that a "countless" number of dead bodies were inside.

Kenya's military says it is conducting "mop up" operations at the site, while Kenya's police urged people to ignore what it called al-Shabab's "propaganda."

Earlier, officials had said they were in control of the mall with soldiers going through the building looking for anyone still inside, and that all of the hostages had been freed.

Fresh gunfire was heard around dawn Tuesday and again about three hours later.

Al-Shabab also repeated its stated reason for staging the attack, posting Tuesday that "peace will come" to the mall when Kenya removes its forces from Somalia.  Kenya has rejected that demand.
