KIEV, Ukraine (AP) - Ukraine's president vowed to increase troop numbers to fend off attacks by Russia-backed separatist rebels and warned his countrymen that there is still the threat of a "large-scale invasion," in an impassioned speech to mark Independence Day on Monday.
Speaking during a military parade, President Petro Poroshenko said Ukraine must not be complacent even though hostilities have largely died down. In a show of force, thousands of Ukrainian servicemen marched in downtown Kiev on to mark the country's independence from the Soviet Union on Aug. 24, 1991.
"We stand for peace, but we are not pacifists," Poroshenko said. "We must get through the 25th year of independence as if on brittle ice. We must understand that the smallest misstep could be fatal. The war for independence is still ongoing."
Poroshenko didn't say how many more troops he would send to eastern Ukraine. He claimed that Russia had massed about 50,000 troops on the border with Ukraine and had supplied the rebels with about 500 tanks and 400 pieces of artillery. Poroshenko warned that Russia is wary of an outright invasion and is instead developing another strategy: sow discord across all of Ukraine and thus spoil its relations with its Western allies.
Poroshenko compared the rebel-held territories in the east and their viability to the evil kingdom of Mordor from J.R.R. Tolkien's "Lord of the Rings" novels.
The Ukrainian troops taking part in the Independence Day commemorations carried rifles but, unlike last year, the parade didn't feature any of the more powerful weaponry as Ukraine is mired in a conflict between government forces and Russia-backed separatists.
The conflict in the east, which has claimed more than 6,800 lives since it began in April 2014, saw a major uptick in violence last week with nine civilians and soldiers killed in just one day.
Ukraine's military said Monday that the rebels violated a cease-fire 82 times overnight in the eastern part of the country, in some cases with large-caliber weapons that should have been withdrawn in line with a truce signed in February.
The presidents of Ukraine, France and Germany are meeting this evening in Berlin to discuss a peaceful solution to the crisis. Moscow is not sending its representative to Berlin, but said it would watch the meeting closely.
A top French official, who spoke on condition of anonymity because he wasn't allowed to speak on the issue, said the gathering was planned as a three-party meeting and that talks also including Russia could be expected "in the next few weeks."
Poroshenko told reporters in Kiev that the meeting is crucial for Ukraine, Germany and France to "coordinate their positions" before a possible meeting with Russian President Vladimir Putin.
On front-line positions in eastern Ukraine, the mood was less festive.
"Today... is a happy day for Ukrainians, but it's an ordinary day for us here on the front line," platoon commander Roman Pikulyk said in the town of Avdiivka. "My heart longs to celebrate, but here holiday feels different, because at war every day is a miracle when one has survived."
