NAIROBI, Kenya (AP) -- Fresh troops have been brought in and multiple barrages of gunfire erupted today at the upscale Kenyan mall where there is a hostage standoff with Islamic extremist attackers.
Officials today raised the death toll to 59 and say the operation is delicate because of the hostages.
Somalia's radical rebel group, al-Shabab, claims responsibility for the attack as retribution for the presence of Kenyan troops in Somalia.
Kenyan authorities say the attackers are holding an unknown number of hostages in the Nairobi shopping center.
Al-Shabab says there will be no negotiations.
Kenyans and foreigners were among those confirmed dead, including two French and two Canadian citizens. Four American citizens were wounded.
