Ugandan authorities beefed up security after receiving warnings that Shabaab may try to execute a Westgate Mall-type attack in Kampala. The US Embassy in Kampala issued a warning on Oct. 15 about the plot. Ugandan police warned on Oct. 2 that wanted Shabaab terrorist Andreas Martin Mueller a.k.a. Ahmed Khaled traveled to Kampala from Limulu, Kenya on Oct. 1. Authorities had looked for Mueller, who is of German origin, when he entered the country in January 2012 along with another Shabaab operative, Emrah Erdogan a.k.a. Imraan Al-Kurdy a.k.a. Salahaddin Al-Kurdy; the two men went to Tanzania, where Erdogan was arrested.
