KYIV, Ukraine (AP) — An emboldened Russia has ramped up military offensives on two fronts in Ukraine, scattering Kyiv’s precious reserve troops and threatening to expand the fighting to a new Ukrainian region as each side seeks an advantage before the fighting season wanes in the autumn.

Moscow's forces made gains in the Kharkiv and Zaporizhzhia regions, according to the Institute for the Study of War (ISW).

Kyiv time on June 30, a total of 111 combat engagements had taken place on the front line over the day, according to the General Staff of the Armed Forces of Ukraine. The heaviest fighting was reported in the Pokrovsk direction.

Demand for Patriot air defense systems and their interceptor missiles is "growing significantly," a RUSI research fellow said.

Gen. H.R. McMaster (Ret.) joins the ‘Brian Kilmeade Show’ to discuss the U.S. decision to pause some weapons deliveries to Ukraine and why he believes Russian president Vladimir Putin is intensifying his campaign.

A halt to supplies of Patriot interceptor missiles is a blow to the embattled country’s efforts to withstand Russia’s mounting and increasingly deadly aerial assaults.

The Kremlin on Tuesday denied claims by U.S. President Donald Trump's special envoy for Ukraine that Russia was stalling in peace talks, adding that Moscow had fulfilled all the agreements reached so far in the negotiations.

Kremlin spokesman Dmitry Peskov has attempted to prove that Russia is interested in peace negotiations following accusations by Keith Kellogg, US President Donald Trump's Special Envoy for Ukraine, that Moscow is deliberately stalling the process.

Russia says it does not want to drag out peace talks with Ukraine, while continuing to pursue its "goals," Kremlin spokesman Dmitry Peskov said. Peskov said that Russia is "grateful" for the efforts by Washington and US President Donald Trump's team to facilitate talks aimed at ending Russia's war against Ukraine.
