Ten hurt as two blasts hit Colombian capital

Bogota

Two minor blasts have rattled the Colombian capital Bogota and injured at least 10 people, amid an uptick in violence and strains in negotiations to end the country's internal conflict. 

The first blast hit in the financial heart of Bogota at about 3:45 pm (2045 GMT) on Thursday, the fire department said on Twitter, reporting a second explosion moments later at an industrial area.

None of the 10 were badly injured but Defense Minister Luis Carlos Villegas branded the blasts "terrorist acts, no doubt." 

The government is in negotiations with rebel groups in Cuba to end the nation's 51-year-old conflict.

The talks have frayed recently, and there has been a surge in guerilla violence.

After the attack, President Juan Manuel Santos pledged to keep fighting "terrorism" while continuing political dialogue.

"We will continue to fight terrorism with the Constitution in one hand and the military offensive in the other, as we have been doing with important results," said Santos, who was in Peru for a conference.

Santos left the Pacific alliance conference to return to Bogota and "evaluate security measures," Interior Minister Juan Fernando Cristo reported on Twitter.
