Need To Know

Pakistan Mosque Bombing

At least 59 people were killed and more than 150 injured in a suicide bombing on a mosque inside a high-security police compound in the northwestern city of Peshawar, Pakistan. More than 300 people were praying at the mosque when the roof collapsed, and many of the victims were police officers.


A commander for the Pakistani Taliban claimed responsibility for the attack on Twitter, while an official spokesperson has denied any involvement. The militant group, also known as Tehreek-e-Taliban Pakistan or TTP, ended a cease-fire with the government in November and has been blamed for a string of recent attacks on security forces and police in the region. Pakistan saw 376 terrorist attacks in 2022, a 28% increase from 2021. The TTP is a close ally of the Afghan Taliban, who seized power in neighboring Afghanistan in August 2021. See an overview of the group here.


The attack comes less than one year after 63 people were killed in a suicide bomb attack on a different mosque in Peshawar.


Colorado Water Cuts

A deadline for seven states to agree on how to reduce their use of Colorado River water hits today as the Interior Department looks to stem historic drops in the system's water volume. The department has warned a lack of agreement would force it to impose mandatory cuts, the first in the system's history.


A 23-year drought—the worst in 1,200 years—has pushed Hoover Dam's Lake Mead to historic lows. The basin supports roughly 40 million people across the lower basin's California, Arizona, and Nevada, and the upper basin's Utah, Wyoming, Colorado, and New Mexico (see map). States have long drawn more water than the river produces, partly stemming from early water managers' math errors. 


The federal government seeks an agreement to cut 2 million to 4 million acre-feet of water usage per year, where an acre-foot equals 1 acre covered by 12 inches of water. See photos of the depleted system here.


Queen of the Skies 

The last commercial Boeing 747, known as the Queen of the Skies and considered the world's first jumbo jet, will be delivered to cargo carrier Atlas Air today, in what is the final rollout of the iconic aircraft. 


The four-engine, hump-shaped 747 is the world’s first twin-aisle airplane. It was first manufactured in 1968 and entered service with now-defunct Pan American World Airways Jan. 22, 1970, enabling people to fly faster and longer distances than before (see background). More than 1,570 models of the aircraft have been created for both passengers and cargo. There are about 358 Boeing 747's still in existence, including two modified military versions of the 747 airliner, which serve the US president.


The newer, more fuel-efficient two-engine Boeing 777X is slated to replace the Boeing 747 in 2025 and will become Boeing's largest aircraft.

See photos of the assembly of the final Boeing 747 here.
