Budapest voiced its opposition to Ukrainian attacks on Russian pipelines that bring oil to Hungary. A Ukrainian attack on a pipeline briefly paused oil deliveries to Hungary.

On Tuesday, Ukraine conducted its largest ever attack on Russia, firing over 300 drones at Russia. While Moscow claimed success in downing the UAVs, some hit their targets, killing at least three people. Also hit was a measuring station on the Druzhba oil pipeline that brings oil from Russia to Hungary. 

Hungarian Foreign Minister Péter Szijjártó responded to the attack by calling on Kiev to halt attacks on energy infrastructure that brings oil into Hungary. Hungary imports most of its oil through the Druzhba pipeline. The pipeline was operational by Tuesday afternoon.

“We consider the attacks directed against the energy structure of Hungary unacceptable,” Szijjártó said. “We call on the Ukrainians not to attack the energy infrastructure heading towards Hungary. Hungary cannot be blamed for the war between Russia and Ukraine, Hungary is not responsible for this war.”

While Kiev and Budapest came to an agreement last year that allowed oil to continue to flow through Ukraine’s section of the Druzhba pipeline, Ukrainian Sanctions Minister Vladyslav Vlasiuk accused Hungary of using the “Druzhba pipeline problem as an argument to block the continuation of sanctions.”

There is some concern within the European Union that Hungary could end the bloc’s sanctions on Russia. Next week, the sanctions, which must be reapproved by every member of the EU every six months, are set to expire. Members of the EU and Ukrainian officials are concerned Hungarian Prime Minister Viktor Orbán will vote against maintaining the sanctions. 

Vlasiuk claimed that Budapest’s policy was undermining “the unity of the EU.”
