Kiev has launched a military operation against eastern Ukraine's independence supporters in April 2014. Despite the signing of a ceasefire deal in February, the sides have since been reporting violations on a daily basis.
"We have increased the number of our troops in the zone of special anti-terrorism operation to 60,000 servicemen," Poroshenko said in an interview with the Inter television.
Poroshenko stressed that the Ukrainian authorities have made strong efforts to arm the units with new or repaired military equipment, to train the personnel in line with Western experience, and to improve logistics and financial support of Ukrainian soldiers.
According to UN estimates, over 6,400 people were killed in the conflict zone in eastern Ukraine since the fighting broke out.
