The United States has delivered 10 armoured but unarmed Humvees as part of its $ 75 million non-lethal military aid deal to Ukraine . Over the next month , a total of 230 of the vehicles is due to arrive in the troubled region to help Ukrainian forces prepare against further attacks from Russian-backed separatists in the east of the country . The U.S. has already sent Ukrainian forces high-tech night-vision goggles , surveillance drones and secure communications systems as part of their commitment . Scroll down for video . The first of 230 armoured Humvees from the United States is unloaded from a C-5 Galaxy transport aircraft . The heavily armoured vehicles form part of $ 75-million worth of non-lethal military aid to Ukraine from the US . The Humvees , pictured , are unarmed , but heavy machine guns can easily be fitted to the roof turrets . Ukrainian President Petro Poroshenko said : ' I have just personally seen - having been behind the wheel of the Humvee - that it is an extremely effective , extremely powerful , extremely good military vehicle which Ukrainian air forces , Ukrainian special divisions , the Ukrainian army are waiting for today . ' He told Ukraine Today : 'And I as the president of Ukraine , as commander-in-chief , on behalf of the Ukrainian people , would like to thank to the United States of America for its comprehensive and firm position regarding the resolution of the conflict in the Donbass , for recognising Russia as an aggressor which annexed Crimea and which launched direct military aggression in particular areas of the Donetsk and Luhansk regions . ' So far , President Barack Obama has decided against equipping Ukraine with offensive military equipment , although the armoured Humvee vehicles donated to Ukraine have turrets which can be easily fitted with heavy machine guns . Fighting in the region has abated although there are some skirmishes still being reported . Although , President Obama has deployed A-10 Thunderbolt ground attack aircraft to Powidz airbase in western Poland . The four tank-killing aircraft are involved in a number of training missions until the weekend . Meanwhile , EU leaders will hold a summit with President Poroshenko in Kiev about the status of the Minsk ceasefire agreement . Ukrainian President Petro Poroshenko , pictured , thanked the United States for the delivery . President Poroshenko said the Humvees were 'very powerful and extremely good military vehicles ' President Poreshenko met with the flight crew , pictured , and representatives of the US Embassy in Kiev . Ukrainian foreign ministry spokesman Yevhen Perebiynis said : 'We expect that the EU-Ukraine summit will take place on April 27 . ' European Commission President Jean-Claude Juncker and European Council President Donald Tusk are expected to attend , as well as EU heads of state and government who wish to go , EU officials added . Trade issues will likely also be on the agenda , the officials said . The summit will be a chance for Poroshenko , who attended an EU summit in Brussels in February , to brief leaders on whether the Ukraine ceasefire deal is fully working and to shape the EU 's decision on whether to extend or lift sanctions on Russia . EU leaders agreed last week that economic sanctions imposed on Russia will stay in place until a Ukraine peace deal is fully implemented , effectively extending them to the end of the year if need be . But they will still have to take a formal decision later on whether to extend economic sanctions on Russia expiring in July . Russia has always denied assertions by Ukraine , backed by the United States and the European Union , that it has been sending arms and troops across the border to support the pro-Moscow separatists . EU leaders will meet President Poroshenko , pictured , in a summit in Kiev next month to discuss the crisis . Despite the reduction in violence , innocent civilians are still being killed and injured as a result of the conflict . Three people were killed and six were injured after the bus they were travelling in struck a landmine in eastern Ukraine . The bus had been in the process of crossing from government to rebel-held territory . A local police official , Ilya Kyva , said the bus had been carrying about 20 passengers from Artemivsk , a government-held town north of the region 's main city of Donetsk , to Horlivka , which is held by the separatists , about 22 miles away . The bus struck the land mine as it apparently tried to negotiate around a road block manned by government forces , Interfax quoted Kyva as saying . Kyva said the six injured people were 'in a serious condition ' . So far , more than 6,000 people have died in the conflict which erupted last April .
Ukrainian President Obama praised the new military hardware . A total of 230 of the heavy-duty vehicles will be delivered over next month . The U.S. has already sent night vision equipment and surveillance drones . President Petro Poroshenko is under pressure to supply offensive military hardware .
