"The prime reason for [Kerry] going to Moscow is of course Syria. It’s impossible to divorce that discussion from what happened in Brussels, particularly if it turns out that… [Daesh] claims of responsibility [for the attack] are true," the official stated on Tuesday.
Earlier on Tuesday, a series of blasts hit Brussels' Zaventem airport and a city-center metro station, killing at least 34 people and injuring almost 200 others. The Belgian authorities are treating the explosions as part of a coordinated terrorist attack.
The State Department representative also noted that Kerry’s discussions with Russian President Vladimir Putin and other senior officials in Moscow would primarily be focused on the Syrian political process, cessation of hostilities and delivery of humanitarian aid.
On Wednesday, Kerry is slated to meet with Russian Foreign Minister Sergei Lavrov to discuss the ceasefire and aid situation in conflict-torn Syria, according to Russian Deputy Foreign Minister Mikhail Bogdanov.
