BBC News reported that both Ukraine and Russia say their air raid alert apps were cyber-attacked. In an explainer, Joe Tidy sets out "what we know so far" about the reported incidents, according to the outlet's summary.

The BBC News summary does not describe the alleged attacks in detail or identify who carried them out. Its headline refers to an alert app hack in Ukraine and Russia.

The Hill reported that Ukraine is accusing Russia of using a localized ceasefire agreement for the border city of Oleshky to shore up its military positions around the city. According to the outlet, the agreement was brokered by first lady Melania Trump.

The Hill added that the truce applied to the Russian-occupied town, located in southern Ukraine, and was meant to deliver critical aid. It began on Tuesday and ended late Sunday, the outlet said. Ellen Mitchell wrote the report.

The Hill's summary does not say how much aid, if any, was delivered during the truce. It also does not include a response from Russia to Ukraine's accusation.

The two reports, from BBC News and The Hill, concern separate matters, one involving communications systems and the other a ceasefire arrangement in the south. Neither summary indicates that the claims in either matter have been independently confirmed, and neither says whether the two developments are connected.
