Historic Merger: The pharmaceutical giant Pfizer will merge with Allergan, the maker of Botox, in what The New York Times calls “one of the biggest takeovers in the health care industry.” The $160 billion deal is the latest attempt by an American company to lower its taxes by reincorporating overseas, a practice called corporate inversion and one that the Obama administration has tried to restrict. Pfizer’s new home: Ireland.

Cameron’s ISIS Strategy: After meeting with French President François Hollande, British Prime Minister David Cameron said he would make a case this week for bombing the Islamic State in Syria in the wake of the Paris attacks. Cameron lost a vote in Parliament two years ago to allow air strikes in Syria following the Assad government’s use of chemical weapons against civilians. British forces are currently carrying out strikes against Islamic State targets in Iraq.

More Raids: After arresting at least 21 people late Sunday and early Monday, Belgian security forces have launched more raids, scouring the Brussels region for suspected terrorists that government officials believe could stage a Paris-like attack.

Gruesome Crime in Indiana: Police have arrested 18-year-old Larry Taylor on a preliminary charge of murder for the death of Amanda Blackburn, a pregnant woman who was killed earlier this month during a home invasion. Authorities believe the intruder raped Blackburn and shot her in the head. Her husband Davey, a pastor, said he was “extremely relieved” to hear the news of an arrest and has chosen a “route of forgiveness, grace and hope.”
