The Ukrainians murdered the 6–person family of Piotr Ostała (according to other sources, the UPA militia murdered a family with a different surname, namely the Ostap family, who were accused of collaborating with the NKVD. A boy named Iwan was supposed to remain alive).

In the village of Silca, poviat Przemyśl, on the road the UPA murdered 6 Poles, including 3 policemen. „On June 28, 1946 in Sólca at 17.30 3 policemen carrying UNRRA provisions were killed by the UPA. One civilian was also killed. The convoy did not know anything that there was a skirmish in this place in the morning, when about 40 Banderites shot at an 8–person Border Patrol Guards WOP patrol. The fight lasted from 9.00—9.30, and the soldiers retreated to the watchtower. The aforementioned policemen formed a patrol from the MO militia post in Rybotycze, returning with provisions. They fell into an ambush organized by a sub–unit of the UPA, numbering about 15 people. It was probably a swarm from 'Udarnyk 4' czota (platoon) 510 from 'Burlak' sotnya. The number of 300 people is also quoted, which is not true. After a short fight, private Tadeusz Hładio and Corp. Ludwik Machunik were killed instantly and Michał Rudawski was wounded and then taken into the forest, where he was murdered. A civilian, Jan Rudawski from Huwniki, and a wounded carter, Michał Hamryszczak, also died. Information about a fallen WOP soldier is also stated, which has no confirmed in the sources”.
