WOODBURY - Authorities say 68 people have been killed and 175 have been injured in Kenya after armed terrorists targeted a bustling shopping mall. More than a day later, authorities say the terrorists are still holding hostages.

Rep. Peter King (R-Seaford) says the Somalia-based Islamic extremist group responsible for the attack has ties to the United States. CNN is also reporting that three of the alleged attackers are from the U.S.

An al-Qaida linked group based in Somalia named al-Shabab claimed responsibility for the attack on Twitter, saying it was in response to the Kenyan government's decision to send troops into Somalia in 2011 to battle the rebels.

King says the Kenyan government has been well-meaning in the fight against terrorism, and that the nation's president is promising a strong response in the wake of the attack.

It's still unknown how many captives are inside the mall.
