Russian and Ukrainian negotiators have arrived in Istanbul for a second round of renewed peace talks on Monday.

Russia`s delegation, led by Kremlin aide Vladimir Medinsky, arrived Sunday, while Ukraine`s team, headed by Defense Minister Rustem Umerov, flew in early Monday.

Turkey`s intelligence chief Ibrahim Kalin is expected to take part in the talks, according to a source in the Turkish Foreign Ministry.

The two sides last met in Istanbul on May 16, when they agreed to exchange 1,000 prisoners each. However, those talks failed to produce a broader ceasefire agreement, let alone a roadmap to end the war, which has been a priority for U.S. President Donald Trump since he took office in January.

Today’s talks come in the wake of Ukraine`s "Operation Spiderweb," a large-scale drone assault involving hundreds of remotely operated drones that targeted multiple Russian airbases and allegedly destroyed dozens of strategic bombers.

Monday`s negotiations are scheduled to begin around 13:00. local time.
