Since 2016, the IceCube collaboration is distributing alerts of high-energyneutrino detections in order to allow follow-up searches for possiblecounterparts. Finding them would provide important clues on the origin of thehigh-energy neutrinos and on the nature of the high-energy cosmic rayaccelerators. We ask for pointed ToO observation of the High Energy StartingEvents and Extremely High Energy neutrinos detected by IceCube and reported inGCNs. We will employ the best available knowledge of the INTEGRAL instruments tohunt for a possible hard X-ray and gamma-ray counterparts. In absence of adetection, we will set the most stringent upper limits. We intend to promptlycommunicate the results of our ToOs to the general community, thus supporting additional multiwavelength follow-ups.

Mission Description
The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations. Since Earths atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis.
