Explosions were heard in Kyiv early Monday morning, as the Ukrainian capital has repeatedly been attacked by Russia through airstrikes.

Kyiv city mayor Vitaliy Klichko announced that the attacks hit the Shevchenko district and urged residents to take shelter. Black smoke and fire was seen near the apparent strike, but it's unclear if there were any casualties.

The explosion sounds were reportedly heard in the same Kyiv district where a missile recently destroyed a children's playground. 

Russian forces have attacked Kyiv consistently with so-called "kamikaze" drones. The Shahed-136 drones, which are manufactured in Iran, have been used by Russia to target vital energy infrastructure and urban centers.

A recent report by the Institute for the Study of War theorized that Iranian Revolutionary Guard Corps (IRGC) troops may have traveled to Russian-held territories to help train Russian troops. 

The use of Shahed-136 drones ramped up after the Russo-Ukrainian War escalated through Vladimir Putin's annexation of the Donetsk, Luhansk, Kherson and Zaporizhzhia regions.

Over the weekend, there was intense fighting around the cities of Bakhmut and Soledar in the Donetsk region, as well as the Luhansk region, according to Ukrainian President Volodymyr Zelenskyy.

The Donetsk region's Russian-backed government claimed on Sunday that its central administrative building was directly hit by Ukraine, but did not report casualties.

Twelve minutes into a "ride-along" with the Texas Department of Public Safety on an early morning shift, a group of migrants was seen hiding in the brush, after swimming across the Rio Grande.

Lieutenant Chris Olivarez with Texas DPS said the migrants making this journey are putting their lives at risk. 

"The number of deaths that have taken place because of this crisis and the amount of immigrants that have lost their lives, is a record number that we have never seen before" Lt. Olivarez said. 

Less than 10 minutes later, a second group was seen on camera and later caught. Lt. Olivarez said it’s not even clear how many migrants are coming across.

"It’s kind of hard to put a number on it because there’s so many people that are coming across. And, there are those individuals that come across that don’t set off any cameras" Lt. Olivarez said.

He said those that aren't detected on camera are referred to as "got-aways," or migrants crossing illegally, who agents can’t catch. 

"Last fiscal year there was almost 400,000 got-aways for fiscal year ’21.. Fiscal year ’22, over 600,000. That’s almost a million known got-aways," Lt. Olivarez said.

Local law enforcement said the migrant crisis is affecting border-towns, like Hidalgo County. Sheriff Eddie Guerra said last week, his office rescued 84 migrants from a tractor trailer transporting them to a "stash house."

"As the sheriff, we have to respond to those bodies that are reported on our side. It really ties up a lot of the resources" Sheriff Guerra said. 

Sheriff Guerra says he’s asking for more secure borders and a change in policy.

"We all agree that there needs to be a pathway of citizenship for these people that are trying to come into the U.S. And make a better life for themselves," Sheriff Guerra said. 

He also said criminal organizations are profiting more than ever from migrants paying them for help with their illegal crossings.
