US Secretary of State Antony Blinken on Friday began a tour of Arab capitals as he seeks to build pressure on Hamas while Israel readies a likely massive offensive on the Gaza Strip following the groups attacks. The top US diplomat will meet Jordan's King Abdullah II, a longtime US partner, and Palestinian president Mahmud Abbas in Amman and will then visit Qatar, Saudi Arabia, Egypt and the United Arab Emirates. Germany has pledged Israel its full support Thursday in the conflict with Hamas, saying Berlin's "only place" right now was at Israel's aide.
