Today's edition of quick hits:
* Crisis in Israel: "Egypt's proposal for a cease-fire between Israel and Hamas collapsed Tuesday only a few hours after the Israelis had accepted it, as Palestinian militants in Gaza launched a barrage of rockets and Israel resumed its airstrikes. The Israeli authorities said a Palestinian attack caused the first Israeli fatality in the eight-day-old military confrontation, in which Israeli bombings have killed nearly 200 Palestinians."
* Ukraine: "Accusations of cross-border hostilities between Ukraine and Russia intensified on Tuesday, deepening a shadowy war of real or imagined attacks and sabotage that threatens to draw the two countries into direct conflict."
* Related news: "The United States is considering imposing unilateral sanctions on Russia over its threatening moves in Ukraine, a shift in strategy that reflects the Obama administration's frustration with Europe's reluctance to take tougher action against Moscow, according to U.S. and European officials."
* Afghanistan: "A suicide bomber blew up a car packed with explosives near a busy market and a mosque in eastern Afghanistan on Tuesday, killing 89 people and wounding more than 40 in one of the deadliest attacks since the 2001 U.S.-led invasion."
* Vargas in custody: "Undocumented immigrant and Pulitzer Prize-winning journalist Jose Antonio Vargas could soon face deportation, according to an immigrants' rights group. Border Patrol allegedly arrested the activist in Texas on Tuesday during his attempt to pass through security at McAllen-Miller International Airport, United We Dream said in a statement."
* Iran: "After three days of intensive talks with his Iranian counterpart, Secretary of State John Kerry said Tuesday that 'tangible progress' had been made in negotiations on Iran's nuclear program, and that he would return to Washington to consult with President Obama over whether to extend a Sunday deadline for a final agreement."
* Fed: "Federal Reserve Chairwoman Janet Yellen on Tuesday joined a chorus of economists downplaying a Commerce Department report that found a 2.9 percent reduction in first quarter GDP growth."
* Russia: "A subway train derailed Tuesday deep below Moscow's streets, twisting and mangling crowded rail cars at the height of the morning rush hour. At least 21 people were killed, Russian officials said, and 136 were hospitalized, many with serious injuries."
* Net neutrality: "The Federal Communications Commission is giving companies, public interest groups and concerned citizens more time to voice their concerns about the agency's plans to rewrite its net neutrality rules."

* They're right: "A majority of Americans think House Speaker John Boehner's lawsuit against President Barack Obama is a pointless waste of resources, according to a new poll. Boehner (R-Ohio) is pursuing a lawsuit against Obama, saying the president used executive power to delay provisions in the Affordable Care Act that should have required congressional approval. While the speaker's proposed lawsuit has the backing of some Republicans in Congress, 51 percent of American voters view it as a "political stunt," according to Public Policy Polling."
