Earlier this week, Polish Prime Minister Mateusz Morawiecki ordered that the first terrorist alert level be introduced in Warsaw in connection with the upcoming conference and that it be in effect from midnight on February 11 to midnight on February 15 (23:00 on February 10 to 23:00 on February 14 GMT)
The two-day ministerial meeting on the Middle East hosted jointly by the United States and Poland, is due to start in the Polish capital on Wednesday. The conference will address such issues as terrorism and extremism, missile proliferation, and security and stability in the Middle East.
Russian Foreign Ministry later announced that it would refrain from participating in the Warsaw conference, calling the meeting a US "political project" aimed at promoting Washington's geopolitical interests within the international community.
