Uganda arrests 19 tied to suspected terror attack plot
No clear evidence the group is directly associated with al-Qaeda-linked al-Shabab
Police in the Ugandan capital Kampala seized "substantial amounts of explosives" and suicide vests in raids on a suspected al-Shabab cell that was planning an imminent attack, a Ugandan official said in an interview on Sunday.
Police arrested 19 people in the operation on Saturday, and Information Minister Rose Namayanja urged the public to "remain vigilant" as Uganda continues its investigation into the planned attack.
"The operation is still going on," Namayanja said. "We just want to ensure that we exhaust all the leads so that there are no more terrorist cells."

Ugandan authorities say they have increased security at hotels and other key sites, including Entebbe International Airport, since making the arrests.
Last week a senior al-Shabab official said the Somali militant Islamist group would target Americans in New York and Washington and "capture Kenya and Uganda."
"Anything could have happened," if the plot had not been foiled, Namayanja said.
She said the government believes the Kampala cell had links to al-Shabab but did not provide evidence linking the two, saying only that al-Shabab has attacked Uganda before.
Leader killed in U.S. drone strike
The discovery of the alleged cell came as Kenya prepared to mark the first anniversary of an al-Shabab attack on Nairobi's Westgate shopping mall in which 67 people were killed.
In 2010, al-Shabab bombed sports bars in Uganda where people were watching soccer's World Cup on television.
Both Kenya and Uganda contribute troops as part of the African Union peacekeeping force battling al-Shabab in Somalia.
The militant group has threatened more attacks since the killing of their leader Ahmed Godane in a U.S. strike earlier this month., reasserting itself in recent days following the death of Godane and the appointment of his successor, little-known Ahmad Umar.
Last week, the group targeted two military convoys near the Somali capital, Mogadishu, and on Saturday militants gunned down a senior Somali national security officer in his car, according to local police and an al-Shabab spokesman.
